/**
* "fire a pointer event" defines as:
* > Before firing this event, the user agent SHOULD treat the target as if the
* > pointing device has moved over it from the previousTarget for the purpose
* > of ensuring event ordering [UIEVENTS]. If the needsOverEvent flag is set,
* > a pointerover event is needed even if the target element is the same.
*
* Thus, pointer boundary events should be fired before `pointerrawupdate`
* event if they are required. This test checks that.
