Description
Describe the bug
-
If instrument changes to unpitched, key signature remains in staff (present in following systems) already reported as #14702
-
If instrument changes to unpitched, transposing score transposes also this unpitched instrument

- If instrument changes to pitched, clef and key signature is missing (also in next system)

If clef is added manualy, it is shown as expected.
3b) But if key signature is added manualy, accidentals are changed, as if keysig were there, but it is not present, nor in next system.

- If Key signature is changed in score, and unpiched instrument is changed to pitched in next bars, staff misses this key change
