Dragging into topmost folder

> **f3579a0** created the issue

The drop target area for the first folder in the list is located **below** the folder's row (top third of the row below) if the list isn't long enough to trigger vertical scroll bars. Instead, the folder's row targets the current directory. If the list is long enough to cause vertical scroll bars to appear it works as expected.

I'm using build 3767.
