(I'm going through old bug reports that have unfortunately gotten no
responses yet.)

I tried your recipe in Emacs 27, and I got:

<!-- <!-\- Blah -\-> -->

So I'm going to go ahead and guess that this bug has been fixed at some
point in the years since the report was filed, and I'm closing this bug
report.  If you're still seeing this, please reopen.
