The other frame affects this because when redisplay redraws a frame,
it temporarily selects that frame, and that selection can resize the
mini-window, something that Lisp programs don't expect to happen.  To
prevent such unwarranted resizing, we disabled it while any other
frame is temporarily selected.  See bug#24285.
