[MuseSounds: Strings] Dynamic changes affect the ending of the previous note

Issue type

Muse Sounds bug

Bug description

Example score: https://musescore.com/user/6436561/scores/10483927?share=copy_link It's most obvious with large jumps and dynamic changes, but also occurs with smaller ones.

This is likely related to https://github.com/musescore/MuseScore/issues/13878 , but even in sections where I'd want portamento, I still wouldn't want to volume level to snap up in the middle of a continuous line. The forte should occur on the note that it's on, not on the end of the previous one.

Steps to reproduce

1. Write a part for any string instrument with a sudden, large dynamic increase
2. Play back the section with MuseSounds
3. Listen for the "bah-dum"--the previous note will suddenly be very loud as it transitions into the next note

it can be temporarily avoided by adding an unnoticeable rest between the notes to prevent the dynamic spike at the end of a note
