Hi Alan, thanks for working on this.

Yes, this seems to fix it in both emacs-27 and master, thanks.

However in emacs-27 with the patch applied I now get a strange
side-effect: After filling the comment, mhtml-mode seems to lose track
of where the JavaScript portion of the buffer is. Please see the
attached image. The position where point is should still be recognized
as HTML+JS, but it's recognized as plain HTML+ instead after
filling. This doesn't happen on master.

I put the version number in the bug subject but forgot to mention it in
the description, sorry about that.
