That's a trick question. I don't know, that's why I said "could be
related". Why did I think so? Because the comment clearly describes a
case where a frame is not "visible" (on the screen) and yet "visible"
(to lisp).
Also, because it does not seem a bug in make-frame (after make-frame,
the frame has visibility = nil as expected); it is only noticeable
after redisplay; or at least, after the command is finished, which
suggests that redisplay was likely triggered.
But I could be wrong, of course. It's known to happen every now and then ;-)
