Layout shift in measure at start of system
Reported in https://musescore.org/en/node/289919, I have attached a simplified example.
1) load attached score
2) select first note
3) hit Down arrow to change pitch
4) observe the first measure of the next system
So far I can say the triggers include having multiple staves with key signatures of different widths - so, different transposition, or pitched and unpitched. The issue also goes away if I delete the title frame or page break on it, which is to say it seems to not occur on page 1.
There are similarities between this and #289892: Bad layout of mmrest at start of system in that it has to do with setting the width of the first measure of a system after a range layout. In this case, we're setting the correct width for the measure when we first decide the system does not need a full layout, but it seems it gets stretched later anyhow, not sure why yet. Also, it's clear the notes are overlapping the key signature segment which shouldn't happen, leading me to think the problem has to do with setting the segment shape or min distance, both things I was messing with recently.
