Hi All,

First, kudos to the authors for this amazing component! :-)

I'm trying to implement two trees, sitting in two independent ControlledTreeEnvironment's. The issue I face is that when dragging item, e.g. 'g1' from the right tree into the folder 'A' in the left tree (see image below), the left tree detects the drag-over event with rather big Y offset.

This offset is not always the same - a small change (a few px) in Y of the dragged object when moving over the root element will cause the drag-over highlight to jump to the next tree item.

Here is an animated gif that illustrates the issue (the dragged object is not visible unfortunately but the cursor is outlined in red)

It looks like some CSS positioning issue but I can't figure out what it could be...
I wasn't sure whether this is a bug or something related to our particular DOM structure, so I thought I'll ask here first :-)

Any help will be greatly appreciated!
