Am I doing something wrong? Is Lilypond doing something wrong? How might I
work around this?
Well, it's only last week that you asked "Is there a way to combine
two voices and print both stems (up and down) when the voices share a
note? \partcombine does not appear to do this by default."
So now you've demonstrated the danger of doing that: it interferes
with the beaming. Isn't the answer just to decide on your priorities?
\partcombine #'(0 . 9) will combine the unison notes and allow the
flag to become a beam in the appropriate direction.
Manually beaming either of the parts (or both, of course) will do the
opposite: produce beams above and below.
Which do you want?
