Default crescendo/decresendo lines not reverting to Style

Changed the Style to position the cresc/decresc markings above the staff and show a wider opening (height) when placed.

When I clicked on a note, then double-clicked on the Crescendo marking in the palette, the line was placed in the correct place but the height was not used. It used the default instead.

When I clicked on the marking, the Inspector showed the height had not been affected and that entry field was greyed out. However, I could change the height manually, but the Reset button next to it didn't revert it to the Style default.
