Comment(by jng):

 Ok the problem is that though visual indicators say you are dropping the
 layer group above the first layer group, the hit detection code says you
 are still dropping that layer group *inside* the first layer group, hence
 the result.

 I'm going to try a 5px vertical buffer from the top of the TreeView, if
 the drop is made within this buffer, it is considered moving the group to
 the top.
