Glissando only working after inserting or removing blank measure after opening .mscz file.

Issue type

General playback bug

Bug description

When I open a new score, Electric Bass guitar, Muse Guitars Vol 1 (everything else default).
I entered a glissando between two notes, then deleted the trailing measures. When played, the glissando does not sound. If I then add an empty measure in front, it does. I saved this file. When I reopen, the glissando does not sound. If I delete the leading empty measure, the glissando sounds. It seems that the glissando does not sound when I open the file until I add or delete a leading measure. Also, please note that when I play the one measure score, it plays for three measures.

Steps to reproduce

Open the .mscz file (in the zip file), play it back. The glissando does not sound.
Delete the first empty measure.
Play it back. The glissando sounds.

Finally, look at the measure counter when playing back. When the score shows 2 measures, it will play for 4. When the score shows 1 measure, it will play for 3.

Please note that I've tried this with LP Electric - Lead as well. Same symptoms.

Preview doesn't always seem to work, so here is a zip file with the .mp4 file.

I first encountered this with Musescore Studio version 4.3.0.241231433 Revision 5f36e74. I don't recall glissandos working in earlier versions of MuseScore 3, but I cannot support that statement with evidence.

The included .mp4 screencast capture does have sound, but I cannot hear it on the preview.
