I must confess I tried to fix it before I create the bug report (as I
usually do since I feel like maintainers are already quite busy...) but
gave up: There are so many regexps to match the function keyword, the
cache, etc.


But I think I've got it working now in Emacs 29.


Thanks a lot! I'll test this this evening.
