I don't understand how that is an issue. It has been mentioned that  
navigating a document which has a fullscreen element would exit  
fullscreen, but not a document.

Indeed the spec lacks document.requestFullscreen. It should be there for  
the traditional fullscreen without browser chrome, just like F11. Or  
instead, mention that calling requestFullscreen on the root would have the  
same effect. I'd rather have it directly on Document though.
