Playing to MIDI plays all the staves despite the selected staves

Issue type

General playback bug

Bug description

When I select a part of my score and play it, the normal behaviour is that it plays only the selected part.

This is not the case with MID I output: all the staves are played.

Steps to reproduce

1. Open a multi-staves score
2. Configure MU4 to play to a MIDI output
3. Select a measure from one staff
4. Play it

Expected: Only the selected measure/staff is played

Actual; All the staff are played

Same workflow and use case as in Staves and voices not played to MIDI output correctly.

Could you take a look at https://github.com/musescore/MuseScore/pull/18827 and confirm if it resolves your issue?

Guess we'd now have to reopen this issue?

I'm not sure to understand the exact status of this issue. Anyway I can't test its fix for now (holidays).

There was a fix, but it turned out to introduce bigger problems, so the fix was reverted and a different solution will need to be found. So there's nothing to test right now, unfortunately.
