0. emacs -Q
1. C-h e
2. (let* ((parent (make-temp-file "my-" t))
          (child  (expand-file-name "child" parent))
          (link   (expand-file-name "link" parent)))
     (make-directory child)
     (make-symbolic-link child link)
     (dired parent))
   C-x C-e

Expected:
- Link target fontified with 'dired-directory' face
Result:
- Link target fontified with undefined 'dired-directory-face' face
- *Messages* says 'Invalid face reference: dired-directory-face'

This seems to be a regression in Emacs 29 (https://bugs.gnu.org/57293):

Use a list of text properties to search in symlink filenames in Wdired

Something like this would fix the problem:

But I don't know whether it's acceptable for emacs-29, or whether it
conses too much during font lock.  In the latter case, we could evaluate
dired-directory-face once (when dired-font-lock-keywords is defined), or
we could use the 'dired-directory' face directly.  WDYT?

Thanks,
