Unwanted naturals showing up in key signatures at the beginning of system

[LittleWishy]

Issue type

Engraving bug (incorrect score rendering)

Description with steps to reproduce

1. Create a score starting with a key signature with any amount of sharps or flats
2. Format -> Style -> Accidentals -> Naturals in key signatures -> select another option besides "Only for change to C Maj / A min"
3. Toggle multimeasure rests (Shortcut: M)
4. Place a key signature change that will show naturals (less sharps or flats, flats to sharps or vice versa, or no accidentals)
5. Place a system break at the key change
6. Close and reopen score

Expected: Naturals should only show up in the courtesy key signature at the end of the first system
Actual: Naturals also show up in the key signature at the beginning of the next system
Current workaround: Disable and reenable multimeasure rests (M x2), correct expected behavior until you close and reopen

Supporting files, videos and screenshots

Expected behavior: courtesy key signature showing naturals Unwanted behavior: system-initial key signature showing naturals
