Aha, you were correct! It's returning an `email.header.Header`
datatype, but it's also doing this for `msg.get('Subject', '(No
Subject)')` which looks like aberrant behavior since the same for
`msg['To']` returns a string!
I may have to raise that as a bug with Python! (Either that or Python
on the mailman system is just old enough that that was fixed later...
Python 3.10)
Either way, I'm starting to figure out what's busted here.

Patches welcome ;-) However, normal type hints in the examples won't
help you here. We'd have to extract attribute references from inside
of function calls, stuff them into type-hinted variables, and use
those. Realistically, to find the type that matters to your problem
you either need to Use the Source, Luke, or RTFM.

Ask not what is the data type of `msg`. Ask instead what is the data
type of `msg['Subject']`. I expect that it's `email.header.Header`.
Try `TID_PATTERN.search(str(message_subject))[0]`.
