I wonder if we need to track full-screen and non-full-screen windows in two
different sets, so that this (and the crash handling) are more focused? I'm
thinking about Chrome being in full-screen mode and the user, say, attaching a
file in Gmail; we don't want Chrome to exit full-screen mode.

Ah, I'd forgotten about browser-side fullscreen mode.  Good point, will take a
look.
