bug#48254: 28.0.50; minibuffer does not show the prompt of a command on first invocation

[max . brieiev]

I can't reproduce this with 'emacs -Q'.

Create '.emacs' file that contains just this single line:

(add-hook 'change-major-mode-hook
          (lambda () (set-input-method "english-dvorak")))

Now start Emacs.

Press 'M-x' or 'C-x C-f' or likely any other keybinding that would
activate minibuffer. Notice that on the first invocation the command
prompt does not appear in the minibuffer. The prompt appears only after
you have started typing command argument or pressing keybinding
repeatedly.
