bug#56725: 29.0.50; face-remapping-alist does not work correctly for mode-line face

[me <pRoMMMModE@outlook.com>]

Hi, I was tring to make the face mode-line dynamic and buffer-local by
remapping it via face-remapping-alist. However the remapping for
mode-line-face does not take effect immediately, in fact I need to
reload current theme or load a new theme; and the mode-line-face across
all buffers are always the same face, even though the buffer local value
of face-remapping-alist have mapped mode-line-face the different faces
in those buffers.

To reproduce the bug:

1. Launch Emacs with emacs -Q.

2. Eval this in scratch buffer:

   (set (make-local-variable 'face-remapping-alist)
     (copy-tree '((mode-line error))))

3. The font color of mode-line of the scratch buffer should change to
red but it does not.

4. Load a random built-in theme like adwaita by M-x load-theme, now the
font color of mode-line changed to red, but all buffer's mode-line' font
also changed to red, in fact open a new buffer will reset the face of
mode-line to the theme's default.

Now sure if it is a expected behavior, I can set a buffer-local
remapping for other faces, so I assume this is a bug.
