Chords symbols attached to fret diagrams lose their custom offsets after Save
Version 3.4.2/3.5 alpha/3.x dev/master (Windows 10)
1) Default score
2) Add the C fret diagram in measure 5 (no matter, just to avoid the Title frame)
3) Select the chord name (C)
4) In Inspector: disable automatic placement
5) "Y" offset: change to - 1 sp.
Result: unexpected, custom offset is lost, chord name is totally misplaced on the diagram.
