Glissando not exporting at all in MIDI MS4 and onward (not matching playback whatsoever)

Your idea

Functional glissandos, that match the MS4 playback, when exporting to MIDI.

Worked in MS 3.7 (Evolution) and before that; once MS4 (and continuing) hit, it has not worked like it used to.

Problem to be solved

From MS4 over to now, this has been an issue; where when you have any glissando on any instrument, it will export the MIDI data correctly (correctly being what the export for a MIDI File would result in; a clean study run, that would copy what was playing back in the MS sound engine.) MS3.7 (Evolution) and before that version, there was no issue with missing glissandos when export to MIDI.

This has been issue for years, and I hope this gets to the right people so this is fixed.

Start by reproducing the issue in MuseScore with a glissando, then compare playback with the exported MIDI file and check the behavior against MuseScore 3.7 and current MS4 or later versions. Done means MIDI export includes glissando data that matches the playback result.
