bug#48691: outline-minor-mode headings not coloured by levels

[ludvig-faddeev]

Have used "emacs-28.0.50 -Q" and "emacs-28.0.50 -q".

Do you get different heading colours for the three heading levels in my elisp 
file
after doing "M-x outline-minor-mode", followed by executing

   (setq-default outline-minor-mode-highlight 'override)

to the headings below.

;;; * heading 1
;; brief body
;;;; ** subheading 1.1
;; brief body
;;;;; *** subsubheading 1.1.1
;; brief body
