delete range first notes keeps key but add accidentals ??

• Oct 31, 2020 - 15:21

How to reproduce:
new score, key with 2 sharps, enter F notes in the first 2 measures, ctrl-del the first 3 notes => D key still there (2 sharps) but F's in the score have accidental #
I could understand D key disappearing by ctrl-del first notes and F getting accidental F#; or key preserved and no accidental on F. But current behaviour seems a strange mixture to me.

I can confirm, but only by ctrl+del each note separately - i.e., one by one.

I've definitely seen this happen too, clearly a bug but I hadn't bothered to figured out the precise steps to reproduce. Re-adding the key signatures fixes it, so workaround is simple. I also suspect the file would be fixed on save/reload, as I am guessing the problem is the internal key signature "map" has become out of sync with the actual score.
