droppable: false issue

[m-kas]

In some cases I would like to use component only for sorting nodes on one level. So I am enabling drag and drop and adding droppable: false to every node. However in that case I can actually drop another node. Please see example:

I have noticed this as well. Nodes are disappearing when dropped on nodes that have dropable: false applied to them. This is demonstrated in both the above fiddle and in the documentation when trying to drop a node onto the "(NOT DROPABLE)" node. Is this intended?
