I think synthesizeMouseEnteredExitedEventsForAllWindows shouldn't be in deliverMoveResizeEvent since there shouldn't be any mouseEnter/Exit events during a resize or move and I can submit another bug for didWindowEnterFullscreen and didWindowExitFullscreen not being called/not posting mouseEvents that I can work on separately..
