Details

We'd basically need to move it from checking stuff on the element to being an event state.  Right now this is one of our UA-sheet revalidation selectors, with this selector:

  *|*:fullscreen:not(:root):not(:-moz-browser-frame)

In practice, matching it is not too bad if we fix bug 1373800 because then we'll try to match :fullscreen first and that's just a state check and pretty much never matches.  So this might not actually be worth doing.
