bug#45392: 28.0.50; read-from-minibuffer sets `this-command` variable to `exit-minibuffer`

Is it what the recently added varible 'current-minibuffer-command'
intended to do?  Then OP could use it like

  (defun test ()
    (interactive)
    (print current-minibuffer-command)
    (read-from-minibuffer "test")
    (print current-minibuffer-command))
