[MU4 Issue] Portamento glissandos break playback for random assortment of instruments

[erinic04]

Describe the bug Portamento glissandos cause the note they are attached to to ring out until the note is played again for a seemingly random assortment of instruments. Saxophone, cornet, and accordion all work fine, but synths, keyboards, and voices don't

To Reproduce Steps to reproduce the behavior:

1. Create a score with portamento glissandos for one of the affected instruments
2. Hear glissando breaking everything

Expected behavior The glissando should not cause the notes to ring out indefinitely

I can also confirm it is the instrument that causes this, not the sound. Loading an external soundfont, it worked when the instrument was set to oboe, but not when it was correctly set to a synth, even with the same sounds.

src/framework/mpe/resources/general_voice_articulations_profile.json is missing a definition for ContinuousGlissando

Any progress on this? Just came up again in https://musescore.org/en/node/345691, and the above comment seems to indicate where exactly the problem lies?
