If the text/html part is not the unique part of the email,
mml-generate-mime does not expand it to a related multipart. This
break uses cases like PGP signing of an HTML email including images.
For instance, if you compose an email with the <multipart sign=pgpmime>
and a <part type="text/html" disposition=inline>, the second part is
not expanded into a multipart related and the images are not included.

Hi,
I would really appreciate if I could receive a feedback on this patch. I
can't send GPG HTML email because of this limitation and this is is also
blocking an issue reported of my org-msg module.
I have attached the patch here as I have fixed a typo in the commit
headline.
Let me know if I need to address this patch to another mailing list.
Regards,
Jeremy

Makes sense. I've now applied the patch to Emacs 28.

An issue has been identified with this patch for which I wrote a fix.
I ran many tests and combination with this additional patch (see
attachement) and I could not find any issue left.
The reason I missed this obvious bug was my configuration using my
`org-msg' module which has an advice on
`mml-expand-html-into-multipart-related' to workaround the limitation
that my previous patch addresses.
The issue originates from the fact that the
`mml-expand-html-into-multipart-related' function returns a list of
list for an untouched part while it returns a simple list for expanded
multipart. The recursive engine of
`mml-expand-all-html-into-multipart-related' is not handling
this. Considering that the `mml-expand-html-into-multipart-related'
function is only used by mml as an internal function, IMO the best
approach is to make it consistent on its potential return values
structure. The patch I am submitting here makes
`mml-expand-html-into-multipart-related' returns a simple list
regardless of if it is a part or a multipart.
