I know it's not helpful, but quick testing with Emacs master (28) seems
to work fine. If I display the html part of an article, move point into
the article buffer, and run (forward-button 1), point moves correctly to
the first button.

Something to be aware of is that, sometime not too long ago, Lars
re-implemented links in article bodies using widgets instead of buttons.
TBH I don't really know what that means, or what the implications are,
but it's probably good to know.
