The slideshow re-asserts fullscreen when a compositor takes it away,
which is what keeps a teacher from being left looking at the library
beside their slides. A compositor that granted it and revoked it
repeatedly would have had this asking forever, in the middle of a Bible
study.
It gives up after five goes. The slides are still on the screen and
Escape still works; only the insisting stops, which is a far better
failure than a window fighting a compositor in front of a room.
