Description

Describe the bug
The trill line seems to be cursed. The trill line now doesn't trill the second staff anymore, though it now trills the "Nachschlag" Grace Notes (there is no english word for it), you can see it in the video. A trill of the grace notes is clearly to be heard, not the case with the normal trill ornament.

To Reproduce
Steps to reproduce the behavior:

  1. Place notes and ornaments like in the video.

Expected behavior
Nachschlag grace notes shouldnt trill with the trill line.

Research direction

Start by reproducing the MuseSounds playback shown in the linked video, using a score with a trill and Nachschlag grace notes on the second staff. Compare the expected behavior with the reported audio and trace the relevant playback behavior until the grace notes no longer trill independently of the normal trill ornament.
