When changing to C-Major/a-minor after multimeasure rest, naturals are not shown/saved
Create a score which some non C-Major/a-minor key sig, add a C-Major keysig in a later measure and some notes, and yet another keysig even later, enable multimeasure rests, result:
I.e. the naturals are shown.
Save, close, re-open (or take attached sample score), result:
I.e. the naturals are lost.
Works as expected in 2.1, so is a regression in 2.2, and still exists in the current 2.3
