Sorry, I don't know what you mean. I have been using multiple frames for a long
time, yes. But I do not directly call `redirect-frame-focus'. I do call
`select-frame-set-input-focus' in various places.
Does that mean that `r-f-f' works for me in general? I really have no idea.

Yes, I was the first to confirm what was reported in bug #11513.

Apparently so.
(That a window manager can accept input passed to a frame that is not on top in
the stacking order is not exceptional. That is (was, at least) true for many w.
mgrs on UNIX, where you could even change the input focus without changing the
stacking order ("foreground") just by moving the mouse over a lower frame.)

That puts (keeps) the input focus in old-frame. So it seems to work as it
should.
(But new-frame has its title and border highlighted as if it had the focus.
Somehow there is a disconnect between the two. But maybe such highlighting is
intended only to indicate the topmost frame? Dunno.)

I know less that you, but I can perhaps test it if you suggest what to test.
