Hi,

there seems to be display bug when using `after-string` to display text 
in resizable minibuffer frames. To reproduce:

1. `emacs -Q --eval "(setq default-frame-alist '((minibuffer . nil)))"`
2. `eval-buffer` with following code:

```elisp
(setq resize-mini-frames t)

(defvar ov (make-overlay (point-min) (point-min) nil t t))

(minibuffer-with-setup-hook
     (lambda ()
       (move-overlay ov
		    (point-max)
		    (point-max)
		    (current-buffer))
        ;; Note the initial newline...
       (overlay-put ov 'after-string "\nHey there, I'm hidden initially 
and will hide again after any space in the input"))
   (read-string "Hi? "))
```

3. Start typing

As stated in the after-string text, it is initially hidden, shows when 
you input some text and gets hidden again every time you type a space.
