Your test case doesn't seem to call
`mml-expand-html-into-multipart-related' -- did you send the wrong test
or the wrong patch or a missing explanation?

But I think this looks like the right thing.

I couldn't for the life of me figure out how to go from MML to shr-rendered
html. MML and MIME are both gibberish to this pattern matching monkey.

So the test case had nothing to do with the patch? Check.
The patch looks "obviously correct", though, so I've applied it to Emacs
28.

The test case terminates with the patch, and doesn't without the patch.
If that's not what you saw, then all bets are off.

Like I said, the test case doesn't call the patched function at all (for
me).
And the test case didn't infloop either before or after the patch.
Perhaps the web page serves out something different for you than for me?

-> mml-expand-all-html-into-multipart-related calls

Perhaps your emacs is not `(fboundp 'libxml-parse-html-region)`.

Hm, so it does -- when I use "emacs -Q". I must have something
somewhere in my .emacs that redefines something in this area.
