manual positioning info not saved

Seems this has probably been reported, but I can't find it.

Windows 7, 0439920

1) create score
2) add a dynamic to any default whole rest
3) drag it elsewhere
4) save
5) close
6) load

Expected result: dynamic is still where you dragged it

Actual result: dynamic is back to default position

Seems some types of markings remember their position, others don't.
