I've found the cause of it.  It's some arcane coding in
candidate_window_p in window.c.  It's trying to move from an active
minibuffer to a (window in a) frame in which it's active, but fails to
check that the frame's MB is the MB we're moving from.  Or something like
that.  When I add that check, it behaves better.

I can't imagine anybody wanting to use it, either.  But if there are bugs
associated with applying my "minibuffer follows selected frame" patch,
they might bite in other circumstances.

Yes.  Either a user will want "normal" frames, or frames without MBs and
a single minibuffer frame.

Yes, I can see that danger.  I won't raise any bug reports for this sort
of thing without first discussing it on emacs-devel.
