script: Let `wheel`, keyboard- and pointerevents be composed when fired by the user agent by simonwuelker · Pull Request #43799 · servo/servo

simonwuelker · 2026-03-31T13:37:14Z

Addtionally, this updates lots of outdated spec links for mouse-related things that have moved from the uievents spec to the pointerevents spec.

Testing: This change adds new tests

Part of #35997
Fixes #37772

✨ Try run (#23800604802) succeeded.

mrobinson · 2026-03-31T14:25:23Z

+        // https://w3c.github.io/pointerevents/#dfn-attributes-and-default-actions
+        // For pointerenter and pointerleave events, the composed [DOM] attribute SHOULD be false;
+        // for all other pointer events in the table above, the attribute SHOULD be true.
+        let composed = !matches!(event_type, "pointerenter" | "pointerleave");
+        pointer_event.upcast::<Event>().set_composed(composed);


Maybe this should happen in PointerEvent::new so that it is applied consistently?

Only pointer events that are caused by a user action should be composed.

In other words, (new PointerEvent("pointerup").composed == false.

That's why the code needs to be here.

Hmm actually the constructor does currently set the composed flag:

servo/components/script/dom/event/pointerevent.rs

Lines 194 to 195 in 11687b3

// See <https://w3c.github.io/pointerevents/#attributes-and-default-actions>

let composed = &*event_type != "pointerenter" && &*event_type != "pointerleave";

let's fix that...

What we do for mouse events is have two constructors, one for system input events and one for synthetic events or constructed events.

Hmm pointerevents are already (mostly) constructed in MouseEvent::to_pointer_event and MouseEvent::to_pointer_hover_event we can set the flags there.

simonwuelker · 2026-03-31T14:42:21Z

I don't think I can write tests for the keyboard-related events because testdriver throws an error:

[2026-03-31T14:37:30Z ERROR script::script_runtime] Unhandled promise rejection: error: Action send_keys not implemented

mrobinson · 2026-03-31T15:30:55Z

I don't think I can write tests for the keyboard-related events because testdriver throws an error:
[2026-03-31T14:37:30Z ERROR script::script_runtime] Unhandled promise rejection: error: Action send_keys not implemented

This should definitely be possible. In addition to the ones in WPT, we have a bunch of tests that trigger mouse and keyboard events via testdriver. These can be found in tests/wpt/mozilla/tests/input-events/.
