I looked at the same thing all morning, and found that
https://lore.kernel.org/git/20221111231910.26769-1-ronan@xxxxxx/
_probably_ was designed to fix the same issue (and I think you agree that
that patch should be used instead of yours because it is more complete in
fixing left-over issues).

However, try as I might, I did not find out yet why it does not apply
cleanly over here (I got side-tracked into range-diff'ing patches
downloaded from the archive, which is quite the challenge and not even fun
because `range-diff` requires commits, not emails, so I side-tracked
myself into teaching `range-diff` to accept mbox arguments).

Maybe you can adjust that patch so it applies cleanly?

Ciao,
Dscho
