One case I'm not sure about is nested fullscreen with iframes. If myblog.com embeds videohosting.com in an iframe and the user fullscreens a video in the iframe, myblog.com could later overlay or replace the video, although it couldn't mute and unmute the audio. If myblog.com is hostile there are already plenty of bad things it can do, but a seamless transition between the real videohosting.com and something else might be new.

I'm not sure if this is important or not, but it would be good to look into.
