Reviewed by Antonio Gomes.

The hole punch rectangle needs to be present if and only if html5
video content is being rendered. Otherwise unwanted content may
show through from behind the browser tab's window.

I am not adding any new tests because the difficulty of testing
for this case outweighs the benefit.
