Legend is broken in pedigree editor

Description

Two problems:

1) When dragging, the dragged item is not visible.
This is a regression, e.g. check FSDemo for how it is supposed to look and compare to how it looks now

2) Vertical scrollbar is always visible in the legend, even when it is not needed. Also when dragging an item, horizontal scroll bar sometimes appears as well as vertical scrollbar is sometimes activated.
(drag an item around the bottom right corner of the screen to trigger this)

It is likely is responsible for at least problem #2
