 `raise-frame' steals focus some time after being called if the frame
 was iconified
Date: Sun, 08 Nov 2015 18:33:34 +0000

1. On a graphical session, do the following:

    (setq other-frame (make-frame))

2. Iconify (minimize) the newly created frame. 

3. Run the following:

    (let ((cur (selected-frame)))
      (raise-frame other-frame)
      (select-frame cur))

Result: Even though that snippet ends with `(select-frame cur)', focus
is left on `other-frame'.


For comparison, try something else:

1. (setq other-frame (make-frame))

2. Switch back to the original frame, and make sure it is covering the newly created frame.

3. Run the following:

    (let ((cur (selected-frame)))
      (raise-frame other-frame)
      (select-frame cur))

Result: other-frame is correctly raised while focus is correctly left on the original frame.

‘raise-frame’ requires an interaction with the window manager.  If the
latter decides that raising a minimized frame will give focus to that
frame that's it.

You might want to look into bug#745 where you can find many references
to window manager behaviors and older discussions on emacs-devel.

Yeah, that makes sense. Thanks for the reference.
I guess we can close this then.
