Sorry, hit the wrong key.

What I wanted to say is that Emacs doesn't have any capabilities to
set input focus to a TTY (or xterm) frame.  It can only do that for
GUI frames, and even then not always.

Also, selecting a frame doesn't mean that frame gets focus, even for
GUI frames.  There's always a selected frame in Emacs, but focus might
well belong to another application, so we could have a situation where
none of the Emacs frames has focus.

So I'm not at all sure how all this description of what happens with
selecting a different frame is relevant to the issue at hand, which
(AFAIU) is about Emacs TTY frames or xterm windows that get or don't
get focus after "C-x #".
