Arpeggio style editor seems to be newly broken in 4.5.0

I'm now finding, new to 4.5.0, that I cannot drag an arpeggio symbol relative to the notes that it is attached to, nor can I use the style editor to increase Distance to note.

This is important for guitar notation, because normally one places the arpeggio symbol outside of the fingering - but now I cannot move the arpeggio symbol away from the notes to make room for the fingering numbers. Example shown below, which I call "fingeris obscuris." :)

In fact, NONE of the arpeggio style editor functions has any effect: not Distance to note, nor line thickness, nor Hook length.

I'm running: OS: Ubuntu 24.10, Arch.: x86_64, MuseScore Studio version (64-bit): 4.5.0-250721848, revision: 7c55023
