I've now committed a fix to mm-with-part that may or may not fix this
nnmaildir problem.  Can you try this (in Emacs 28)?  You may have to do
a "make bootstrap" or at least remove all the lisp/gnus/*.elc files for
the change to have any effect.

If it works for you in Emacs 28, we may backport it to Emacs 27.  I
think it should be safe (famous last words).
