Arpeggios positioned completely wrongly when endpoints moved

Issue type

Engraving bug

Bug description

Take this:

and extend the arpeggio down to the lower stave:

The positioning gets totally mangled.
In fact, this happens as soon as either endpoint of the arpeggio is moved vertically at all, even within the same stave.

This is a regression since 4.1.1, which gives this:

(If, in the process of fixing this, it's possible to improve the placement so that it takes accidentals on the lower stave into account - which has never worked - then even better):
