The direction of beamed notes does not immediately change when the beam is broken
In the attached score, select the last note in measure 2, open the beam properties palette, and select "beam start" to break the beam. Observe that the direction of the beamed notes does not change. Compare with the same notes in measure 3. Also note that the beams in both measures have the direction set to "auto". The direction of the beamed notes will be incorrect until a relayout occurs.
