The type given in the warning is nonsensical for negative duration logs.
The type of the stem is determined from the first of the parallel notes
for this voice, and if that does not match the type of the other
parallel notes, no consistent result can be output (you only get one
stem per voice).

I don't think there is a point to turning a fixed problem into an issue
unless there is a problem with the fix.
