So...  The trade-off is:

1) Only browsing contexts can go full-screen (since they have URLs
that we could display).
2) Any element can go full-screen, but we'll need to add a nasty
non-semantic attribute.

Another idea is that we could let any element go full-screen, but then
we'd show the URL of its browsing context.  There's some subtleties
here about overlays from parent frames, but those seem solvable.
