=============================================================================
;;; In Emacs 28.1, using ':eval' in 'frame-title-format' doesn't work like it
;;; used to in Emacs 27 and earlier. In fact, it is completely broken, if one
;;; uses a frame-parameter in ':eval'.
;;;
;;; The following elisp snippet demonstrates the problem in an Emacs 28.1
;;; instance started with 'emacs -Q'
(defun title-suffix ()
(cdr (assoc 'title-suffix (frame-parameters (selected-frame)))))
(defvar title-prefix "Test")
(setq frame-title-format (list title-prefix '(:eval (title-suffix)) " %b"))
;;; The original frame should show a frame title of 'Test *scratch*'
(set-frame-parameter (selected-frame) 'title-suffix "")
;;; The next frame created should show a frame title of 'Test-xxx *scratch*'
(make-frame-command)
(set-frame-parameter (selected-frame) 'title-suffix "-xxx")
;;; The third frame created should show a frame title of 'Test-yyy *scratch*'
(make-frame-command)
(set-frame-parameter (selected-frame) 'title-suffix "-yyy")
;;; In Emacs 27 and earlier, that is exactly what happens. Selecting a
;;; different frame doesn't change the titles of all other frames.
;;; In Emacs 28.1, all frames show the same frame title, with the last one
;;; selected determining which one is shown for the bunch of them. Changing to
;;; a different frame changes the titles of all frames to the title of the
;;; newly selected one.
