Good point. Will update the patch.

If we put all these details behind and look from the users' perspective,
I wonder if there is a chance for Emacs 28.

Basically this feature has been there and working since at least Emacs
24 (or even earlier). It may be an accident which I only discovered last
week though the bug has been annoying me for a few months since I
upgraded from Emacs 27. For users this is a regression and it's bad.

Comments?
