Beam Middle not working across barlines
Notes immediately before and after a barline can no longer be beamed together.
Steps to reproduce with the attached score...
1. Select the first note of measure 10 (the Eb4 sextuplet quaver).
2. Expand the Beam Properties group in the palette.
3. Double-click "Beam middle".
Result : No change to the beaming of either the Eb4 note or the preceding Gb4 in measure 9. In previous versions, the two notes would be beamed together, with the beam drawn across the barline.
