bug#56305: 29.0.50; 'yes-or-no-p' deselects minibuffer frame

[martin rudalics <rudalics@gmx.at>]

With emacs -Q --load "~/mini.el" which contains the three lines

(setq use-dialog-box nil)
(setq default-frame-alist '((minibuffer . nil)))
(shell)

and type C-x C-c in the minibuffer frame.  This asks a 'yes-or-no-p'
question in the minibuffer frame but selects the *Process List* window
on the other frame.

FWICT this worked correctly until Emacs 26, was broken in Emacs 27,
returned to work in Emacs 28.1 and is now broken on both, release and
master branch, again.
