Behavior

When pushing a FormGroup inside a FormArray, can it be possible to prevent the push to emit an event as it is on setValue.

(myForm.get('control') as FormArray).push(new FormGroup(), { emitEvent: false });

What is the motivation / use case for changing the behavior?

When using formArray with a redux store, If I'm using valueChanges observable to dispatch the changed values in my store, the push of a new FormGroup will trigger an endless loop
