A key signature changing fails after undo-redo
GIT commit: 073fcdc / Windows7
1) "My First Score"
2) Add a key signature with 2 flats in the first measure (rather by drag and drop, if not, by double-clicking, another reported issue appears : the measure remains hightlighted)
3) Add a C/Am key signature (so, without flats and sharps) in measure 6, ie the second of the second system.
4) Undo twice
First unexpected result: no more key sig in the first measure
5) Redo twice
Other unexpected result: four flats in measure 5

This issue occurs on last June 3.
Many commits this day. But this nightly works as expected: 41b89ae
Not this one: a41b109
Doesn't know where is the cause. Maybe elsewhere, but after a prompt overview, eg, I read « undo-redo » in this commit (around the end) ? https://github.com/musescore/MuseScore/commit/8de3e55b871166cbe0130970d…
Still actual.
The child of #271331: [EPIC] Positioning, symbols, notation related issues
I'm guessing that the first unexpected result is not that there is no more key signature in the first measure, but that the key signatures at the beginning of the other systems are not removed as well. After all, step 4 should undo step 3, and then undo step 2.
Seems to be not actual for the current master.
