Short trills/mordents playback intervals fixed to major 2nds and cannot be changed

Issue type

Muse Sounds bug

Bug description

Playback of short trills and mordents using Muse Sounds always uses a major 2nd as the interval above/below, even when the default interval (diatonic) is selected. Trying to fix the interval to a minor/major 2nd does not work. (Does not affect playback with MS Basic/soundfonts.)

Steps to reproduce

1. Create new score with Muse Sounds instruments
2. Enter some notes
3. Add short trills or mordents to any of the notes
4. Press play
5. (Optional) In Properties -> Ornament, try modifying interval above/below from Auto (diatonic) to minor/major 2nd, before pressing play again

MuseScore Version

4.2.0-233521125, revision: github-musescore-musescore-eb8d33c

Regression

Yes, this used to work in a previous version of MuseScore 4.x

Operating system

macOS 13.6 (Arch.: x86_64)

Additional context

Seemed to work as expected for previous release of MuseScore (version 4.1.1), so possibly a regression? Other ornaments (e.g. trills, turns) also still work properly, i.e. their intervals can be adjusted and played back correctly.

Soundfonts (MS Basic) plays back all ornaments (including short trills and mordents) as expected.
