Setting lyrics y-offsets in parts doesn't survive save/close/open
In a score with parts and lyrics, in the part set a lyrics offset away from default, e.g. y-offset from 3 to 7
save, close, open.
expected result: offset is still the same
actual result: offset is back to default values (x:0 y:3, but shows those as not being the defaults, i.e. the reset button is enabled)
Observed in 3.2.3 and 3.3RC
MuseScore 2.3.2 doesn't have this issue -> regression
