Subject: 28.0.50; error doesn't use help-key-binding face from substitute-command-keys

Severity: minor

In "emacs -Q", if I use the following function:

(defun foo ()
  (interactive)
  (error (substitute-command-keys "Use \\[next-line]")))

The error message says "Use C-n", but "C-n" is not displayed with the
`help-key-binding' face.

In contrast, `message' does not have this problem:

(defun foo2 ()
  (interactive)
  (message (substitute-command-keys "Use \\[next-line]")))

Here, "C-n" is displayed with the correct face.
