Great! Thanks! I’ll merge this in some time once I figure out whether
should we apply it to emacs-29 or master.
Meanwhile, it seems that you’ve recently working on tree-sitter modes.
If you’re interested, maybe you can take a look at ert-font-lock, and
add some tests that cover the bugs your patches fixes? This is
completely optional, of course. I bought it up because I think you might
be interested.
