Ottavas: "Line properties…" displays the wrong value for font-size
See attached file.
Apply an 8va line somewhere. Change the text size of the 8va in the "line properties box." Exit the box. Note that the text size does indeed change. Then view the text size again. It has reverted to the default 12. It may be an issue with 8vbs as well.
Another issue: Offset values are lost when you copy and paste measures with 8vas (and 8vbs) in them.
