Re: [fullscreen] Inconsistency of condition between entering fullscreen and exiting fullscreen (#6)

We have two ways to resolve this issue. The stricter one is to change the ready check condition and disallow any element to enter fullscreen if there has been something in the top layer which does not have fullscreen flag.

The looser one is to change the "collect ancestors" step and make it collect a document if the top layer contains only one element which has fullscreen flag set.

I guess the stricter one makes more sense given the current spec where it is not allowed to have discontinuity between fullscreen elements in the top layer.
