Summary:
changelog: [internal]
FabricEventDispatcher does not need to run on every frame. Whenever a new event is added to Fabric's event queue, it will call
FabricUIManager.onRequestEventBeat
in Java. This in turn callsFabricEventDispatcher.maybePostFrameCallbackFromNonUI
and adds a frame callback on the Choreographer.This makes code simpler, as we do not need to manage the frame callback subscription.
