Glissandi where the end note has the "play" flag off play back incorrectly via muse sampler

Issue type

Muse Sounds bug

Description with steps to reproduce

1. Create a score using, e.g. Muse Strings, with 3 notes all at different pitches and add a glissando line between the first two.
2. Confirm the playback is as expected
3. Now turn off the "play" flag for the middle note.
4. Repeat playback - observe that the glissando is played between the wrong notes. This happens even if a rest is placed before the 3rd note.

Comparison of MS Basic gliss to note with play-flag off vs Muse Sounds (happens with almost any library etc.)

What is the latest version of MuseScore Studio where this issue is present?

4.4

Regression

Yes, this used to work in MuseScore 3.x and now is broken

Operating system

Windows 11

Additional context

Have reported via Muse Hub but it does appear to be an issue in the playback rendering code inside MuseScore itself, as it never sends any information about the silent note to the sampler.
Doesn't happen with MS Basic.
Note that what I'm trying to achieve is a glissando that doesn't end on a sustained pitch at all, i.e. a "fall off".

Checklist

• This report follows the guidelines for reporting bugs and issues
• I have verified that this issue has not been logged before, by searching the issue tracker for similar issues
• I have attached all requested files and information to this report
• I have attempted to identify the root problem as concisely as possible, and have used minimal reproducible examples where possible

Reproduce the issue with the linked score using the listed steps, then inspect MuseScore's playback rendering code, especially how glissandi and notes with the play flag disabled are represented for Muse Sounds. Done means the glissando uses the intended notes and supports the described fall-off behavior without changing the MS Basic result.
