This seems to work:

(let ((f (selected-frame)))
  (with-selected-frame (make-frame)
    (switch-to-buffer (get-buffer-create "other")))
  (select-frame-set-input-focus f)
  (let ((win (get-buffer-window "other" t)))
    (when win
      (with-selected-window win
        (recenter 0)))
    (let ((w (selected-window)))
      (unwind-protect
          (progn
            (select-window (minibuffer-window))
            (fit-window-to-buffer)
            (read-key (propertize "hello" 'face '(:height 2.0))))
        (erase-buffer))
      (select-window w))))

As well as this (which is a minor variant of your original recipe);

    (let ((f (selected-frame)))
      (with-selected-frame (make-frame)
        (switch-to-buffer (get-buffer-create "other")))
      (select-frame-set-input-focus f)
      (let ((win (get-buffer-window "other" t)))
        (when win
          (with-selected-window win
            (recenter 0)))
        (with-selected-window (minibuffer-window)
          (unwind-protect
              (read-key (propertize "hello" 'face '(:height 2.0)))
            (erase-buffer)))))
