The following pattern is often used in scrolling tests: eventSender.monitorWheelEvents(); await UIHelper.mouseWheelScrollAt(50, 50, 0, -10); await UIHelper.waitForScrollCompletion(); This doesn't work when UI-side compositing is enabled, because the UI process may not have committed a new layer/scrolling tree by the time that the first wheel event is handled in the UI process. This is because layer/scrolling tree updates happen via updateRendering() on a 60fps cadence, but `UIHelper.mouseWheelScrollAt` sends events via async IPC, which can get to the UI Process first.
