bug#53241: 28.0.50; kbd macro repeat twice when using (setq unread-command-events ...) &co

[calcium]

Steps to reproduce

eval :

(defun do-C-n ()
  (interactive)
  (setq unread-command-events
        (listify-key-sequence
         (kbd "C-n")) ;; => '(14)
        ))

then, go to line 1, type <F3>, M-x 'do-C-n', <F4>.
Notice you have landed at line 2. Return to line 1.
Do <F4>. The bug is that we are now at line 3, instead of line 2 ...
