bug#23204: 25.1.50; Strange behaviour of ‘read-char’

I also don't quite understand why this happens, but it seems that
using (message nil) to clear the minibuffer also works:

(defun my-command ()
  (interactive)
  (message nil)
  (while (read-char "My prompt…" t)))

(global-set-key (kbd "<f12> t y") #'my-command)

(I can't bind <menu> t y in emacs -Q, I get an error message telling
me <menu> is not a prefix key)
