I haven't used "buttonised" article display in yonks, but I think cid:
basically works for me in the articles (I mean spam) I see, and they are
usually multipart/alternative wrapped in multipart/related, I seem to
remember from the last time I looked at it.

Could you forward a complete message that displays the issue?
