Let me just clarify one thing. A browser's built-in "get out of
full-screen" user gesture will probably need to break out of all nested
fullscreen requests for security reasons. However, in-page UI to exit
full-screen (such as a button in pop-up video controls) should still be
able to return to the previous full-screen presentation.

"If we claim to be without sin, we deceive ourselves and the truth is not
in us. If we confess our sins, he is faithful and just and will forgive us
our sins and purify us from all unrighteousness. If we claim we have not
sinned, we make him out to be a liar and his word is not in us." [1 John
