bug#17736: 24.4.50; *-mouse-1 acts on wrong frame

[Drew Adams]

> Do you have a working recipe that demonstrates this bug?

Sorry; forgot that.  Use this simpler file instead:

------------8<------------------

;; runemacs.exe -Q --debug-init  -l "onetest.el" -f "1on1-emacs" "onetest.el"

(defun 1on1-emacs ()
  ""
  (interactive)
  (setq default-frame-alist
        (list
         '(font . "-*-Lucida Console-normal-r-*-*-14-*-*-*-c-*-iso8859-1")
         '(bottom-divider-width . 2)
         '(minibuffer)))
  (setq pop-up-frames  t)
  (setq minibuffer-frame-alist (list '(height . 2)
                                     '(minibuffer . only))))
(global-set-key [C-S-mouse-1]
                (lambda () (interactive)
                  (message "FR: %S" (selected-frame))))

And I should have said that after step 3 use C-g
or whatever to end that step's M-x.  And select the
*scratch* frame.  IOW, step 4 is a repeat of step 3,
except that you do C-S-mouse-1 in the same frame,
*scratch*, not in another frame.

I just checked, and the same bug exists from Emacs
24.5 through 27.1.  IOW, it's still there.
