Timothy Flynn ad3c63684c LibWeb: Restrict toggling video playback to certain areas in a video
When the control bar is shown, do not toggle playback when clicking on
the control bar, unless the click target is the playback button. This
will let us implement clicking on the timeline to seek.

Note that this requires caching some layout rects on the video element.
We need to remember where the corresponding layout boxes are, and we
can't cache them on the layout box, as that may be destroyed any time.
