bug#33244: 27.0.50; buffer-local face-remapping not obeyed for the fringe

[Stefan Monnier <monnier@IRO.UMontreal.CA>]

Package: Emacs
Version: 27.0.50


If I do:

    src/emacs -Q --eval "(face-remap-add-relative 'fringe '(:background \"red\"))"
    C-x 4 b *Messages*
    M-x redraw-display
    C-x o
    M-x redraw-display

I see that Emacs redraws all the fringes with the same `fringe` face, that which
happens to be specified in the currently selected window, instead of
correctly using for each window the `fringe` face adjusted to the
face-remapping that happens to be active in the window's buffer.
