Repitch mode skips or gets stuck on grace notes

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

When using repitch mode, the cursor auto-advances to the next note, but it skips over grace notes that are before a regular note. Also, it seems to get stuck on grace notes after a regular note; the cursor remains on the note with the grace after, and can't advance past it.

• I have attempted to identify the root problem as concisely as possible, and have used minimal reproducible examples where possible

Start by reproducing the issue in repitch mode with grace notes before and after regular notes, using the attached video as a reference. Trace the cursor's automatic note advancement and identify how grace notes are handled in both positions. Done means the cursor visits each intended note once and can advance past grace notes without becoming stuck, with regression coverage added if the relevant test area is found.
