Ties across key changes with accidentals are incorrect
Steps to reproduce:
- Create piece with key change from G to Ab.
- Input the note C tied across the key change.
- Use the arrow keys to move this down a semitone.
The note displays as Cb (correct for final key) across both parts of the tie.
The note displays as B before the key change and as C after it
Basically, the two parts of the tie aren't properly linked, so they both display correctly for the key they belong to, regardless of whether that makes them appear differently to their counterpart.
Workaround: enter the accidental manually from the palettes.
