Yes, we should probably just do that.

So I propose that a "toplevel" class be set on the root element of a media
resource document in a toplevel browsing context.

"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
