I'm having problems with a slur ending on a note with the early classical
ornament \prall\turn.
Sometimes the slur ends between the \prall and the \turn and their order
is
inverted, the prall coming below the turn instead of above. But it's very
context-dependent, and it took some experiment to find a minimal example.
Even when the slur doesn't collide with \prall\turn, it usually ends above
the ornament instead of near the note, as in the example below.
If you uncomment the last two lines of the example, it changes the
behaviour
of the slurred prall-turns earlier in the example: the slurs end above the
prall instead of in the middle.
