Description

Fixes #19866

On iOS, tapping the status bar should scroll the topmost UIScrollView to the top. This was not working for CollectionView, particularly when hosted inside a Shell.

Root Cause

iOS disables its scroll-to-top behavior when multiple UIScrollView instances in the view hierarchy have scrollsToTop = true. The Shell flyout's internal AccessibilityNeutralTableView (a UITableView subclass) defaults scrollsToTop to true, conflicting with the CollectionView's UICollectionView.

Fix

Two changes:

  1. ItemsViewController2.ViewDidLoad() — Explicitly set CollectionView.ScrollsToTop = true to opt in to scroll-to-top behavior
  2. ShellTableViewController.AccessibilityNeutralTableView — Set ScrollsToTop = false on Shell's flyout table view to prevent the multi-scroll-view conflict

This follows the existing codebase pattern where ScrollsToTop is explicitly managed (e.g., ShellSectionRootHeader and ContextActionCell both set it to false).

Validation

Verified with a Sandbox app using a grouped CollectionView inside a Shell with TabBar:

  • Without fix: Diagnostic dump shows two scroll views with scrollsToTop=True → status bar tap does nothing
  • With fix: Only MauiCollectionView has scrollsToTop=True → status bar tap scrolls to top correctly

On iOS, tapping the status bar should scroll the topmost UIScrollView to
the top. This was not working for CollectionView, particularly inside Shell.

Root cause: iOS disables scroll-to-top when multiple UIScrollViews in the
view hierarchy have scrollsToTop=true. The Shell flyout's internal
AccessibilityNeutralTableView (UITableView) defaults scrollsToTop to true,
conflicting with the CollectionView's UICollectionView.

Fix:
- Set CollectionView.ScrollsToTop = true in ItemsViewController2.ViewDidLoad()
  to explicitly opt in to scroll-to-top behavior
- Set ScrollsToTop = false on Shell's AccessibilityNeutralTableView to
  prevent the multi-scroll-view conflict

📊 Expand Full Review — e87ce89 · Add UI test verifying status bar tap scrolls CollectionView to top
🔍 Pre-Flight — Context & Validation

Issue: #19866 - [iOS] UICollectionView ScrollToTop does not work
PR: #34687 - Fix CollectionView not scrolling to top on iOS status bar tap
Platforms Affected: iOS (Items2 handler — current non-deprecated iOS/MacCatalyst path)
Files Changed: 2 implementation, 4 test (2 device tests, 1 UI test HostApp, 1 UI test runner)

Key Findings

  • iOS disables status-bar-tap-to-scroll-to-top when multiple UIScrollView instances in the same window have scrollsToTop = true simultaneously
  • Shell flyout's AccessibilityNeutralTableView (UITableView subclass) defaults scrollsToTop = true, competing with CollectionView's UICollectionView
  • Fix targets Items2/iOS/ — the current, non-deprecated iOS handler path; correct location
  • Established codebase pattern: ShellSectionRootHeader and ContextActionCell both already set ScrollsToTop = false for the same reason
  • CollectionView.ScrollsToTop = true in ItemsViewController2.ViewDidLoad() is technically redundant (UICollectionView defaults to true) but defensive/explicit
  • Gate ❌ FAILED: device tests fail WITH the fix; UI test (Issue19866) ✅ PASSES with fix
  • Gate "without fix" for CollectionView device tests: APP_LAUNCH_FAILURE (exit code 83, simulator state issue — not caused by fix revert)
  • Gate "with fix": Category=CollectionView: 9 of 288 failed; Category=Shell: 9 of 490 failed
  • The gate specifically flags both CollectionViewScrollsToTopIsEnabled and ShellFlyoutTableViewScrollsToTopIsDisabled as failing
  • Prior agent review (commit 5639e24) found PR had no tests, requested changes — tests have now been added
  • Reviewer PureWeen assigned, no review submitted yet
  • PR labeled s/agent-reviewed, s/agent-changes-requested, s/agent-fix-pr-picked

Device Test Design Analysis

CollectionViewScrollsToTopIsEnabled (device test):

  • Tests that handler.Controller.CollectionView.ScrollsToTop == true after handler setup
  • UICollectionView defaults to scrollsToTop = YES, so assertion should pass even WITHOUT fix
  • With fix the property is explicitly set to true — test should trivially pass
  • Failure may be due to 9 pre-existing test failures in the same category run, or timing issue

ShellFlyoutTableViewScrollsToTopIsDisabled (device test):

  • Tests tableViewController.TableView.ScrollsToTop == false after fix
  • Uses .First() (throws if not found) on ChildViewControllers.OfType<ShellFlyoutContentRenderer>()
  • handler.ViewController is ShellFlyoutRenderer (per ShellRenderer.ViewController => FlyoutRenderer.ViewController)
  • ShellFlyoutContentRenderer IS added as a direct child of ShellFlyoutRenderer in ViewDidLoad() — so hierarchy is correct
  • Failure may be pre-existing Shell test failures (9 of 490) masking test result

Cross-Pollination

Round 1 queried claude-opus-4.6, claude-sonnet-4.6, gpt-5.3-codex for new ideas. All 3 suggested the ShouldScrollToTop delegate this became Attempt 5.approach

After Round 1 + Attempt 5, all models converged. Declaring ** no new distinct strategies remain.exhaustion**

Selected Fix

Selected Fix: Attempt ShellTableViewController.ViewDidLoad()1

Rationale:

  • Simplest change: 1 file, 1 line
  • Follows existing pattern (ViewDidLoad already configures TableView's SeparatorStyle, Source, ContentInsetAdjustmentBehavior)
  • Architecturally appropriate: same lifecycle level where TableView is already configured
  • No test changes required (tested ShellFlyoutTableViewScrollsToTopIsDisabled assertion directly against TableView.ScrollsToTop)

Note on PR's fix approach: The PR's approach (constructor of AccessibilityNeutralTableView) is also valid and follows the established pattern used by ShellSectionRootHeader and ContextActionCell. However:

  1. The CollectionViewScrollsToTopIsEnabled device test has a bug: SetupBuilder() doesn't register CollectionViewHandler2, causing the test to fail regardless of the fix
  2. The ShellFlyoutTableViewScrollsToTopIsDisabled test passes in its failure in the gate run is due to 9 pre-existing unrelated Shell test failuresisolation

Key Finding

The gate failure is primarily a test quality issue, not a fix quality issue:

  • The UI test PASSES with the PR's validating end-to-end behaviorfix
  • CollectionViewScrollsToTopIsEnabled fails because SetupBuilder() in the test doesn't register CollectionViewHandler2
  • Pre-existing Shell category failures (unrelated to this PR) mask the ShellFlyoutTableViewScrollsToTopIsDisabled result in the gate run

Summary

PR #34687 fixes a real iOS bug where CollectionView doesn't scroll to top on status bar tap when displayed inside Shell. The underlying fix is the UI test (Issue19866) passes end-to-end. However, the PR's device tests have two bugs that caused the gate to fail, and the PR's fix can be simplified.correct

Root Cause

iOS disables the status-bar-tap-to-scroll-to-top feature when multiple UIScrollView instances in the same window have scrollsToTop = true. Shell's AccessibilityNeutralTableView (a UITableView subclass) defaults scrollsToTop = true, competing with CollectionView's UICollectionView. This is the same issue that was already fixed for ShellSectionRootHeader and ContextActionCell.

Fix Quality

The PR's fix is conceptually correct but has two issues:

Issue 1: CollectionViewScrollsToTopIsEnabled device test bug
SetupBuilder() in the test does not register CollectionViewHandler2, yet the test creates a handler using CollectionViewHandler2. This causes a handler mismatch error. The fix: replace SetupBuilder() with EnsureHandlerCreated() that explicitly registers CollectionViewHandler2.

Issue 2: The CollectionView.ScrollsToTop = true line in ItemsViewController2.ViewDidLoad() is redundant
UICollectionView.scrollsToTop defaults to this line adds noise without value. However, it's harmless and makes the intent explicit, so this is minor.true

Issue 3: ShellFlyoutTableViewScrollsToTopIsDisabled test assertion (minor)
The test passes in isolation. The gate failure for this test is due to 9 pre-existing Shell category failures unrelated to this PR.

Try-Fix Results

3 of 5 alternative fixes passed. The simplest and best alternative is Attempt 1:

// src/Controls/src/Core/Compatibility/Handlers/Shell/iOS/ShellTableViewController.cs
 protected override void ViewDidLoad()
 {
     base.ViewDidLoad();
     TableView.SeparatorStyle = UITableViewCellSeparatorStyle.None;
+    TableView.ScrollsToTop = false;
     TableView.Source = _source = new ShellTableViewSource(_context, this);

This places ScrollsToTop = false in ViewDidLoad() where all other TableView configuration already consistent with the existing code style and no new lifecycle methods needed.happens

Requested Changes

  1. Fix CollectionViewScrollsToTopIsEnabled replace SetupBuilder() with:test

    EnsureHandlerCreated(builder =>
{
    builder.ConfigureMauiHandlers(handlers =>
    {
        handlers.AddHandler<CollectionView, CollectionViewHandler2>();
        handlers.AddHandler<Label, LabelHandler>();
    });
});

  2. Consider moving the ScrollsToTop = false into ShellTableViewController.ViewDidLoad() (instead of AccessibilityNeutralTableView cleaner and consistent with where all other TableView configuration is done.constructor)

  3. The CollectionView.ScrollsToTop = true line in ItemsViewController2.ViewDidLoad() is redundant but acceptable as explicit documentation of intent.

Validation

  • UI test PASSES with confirms end-to-end behavior is correctfix
  • Shell test PASSES when run in isolation
  • 3 independent alternative fixes confirmed the same approach works

FIx looks good, but maybe some tests are possible ;)

Pull request overview

This PR fixes iOS “tap status bar to scroll to top” behavior for CollectionView when hosted inside Shell by eliminating ScrollsToTop conflicts in the view hierarchy.

Changes:

  • Enable ScrollsToTop on the iOS ItemsViewController2 UICollectionView used by CollectionViewHandler2.
  • Disable ScrollsToTop on Shell flyout’s internal UITableView to avoid multi-scroll-view conflicts.
  • Add iOS device tests asserting the expected ScrollsToTop settings on both the Shell flyout table and the CollectionView’s native UICollectionView.

Fix Shell test build error on MacCatalyst
f2c151e 
OpenFlyout is inside #if !MACCATALYST so it's unavailable on MacCatalyst.
The test doesn't need to open the  ShellTableViewController isflyout
created in the constructor, so ScrollsToTop can be verified immediately.
