Able to drag a parent under a child in Grid when multiselect

V1.6

We have the following structure in the grid:

A
----B
----C
--------D
----E

If we multiselect nodes C and E, then drag the group by selecting E and dragging to D, the grid will allow this and the grid gets corrupted. The grid shouldn’t allow C and E to be dragged until D because C is already the parent of D. If we multiselect C and E then drag C to D, the grid will not allow this. It’s only when the actual dragging occurs by any other node but the first node in a multiselect.

Are there any workarounds for this?
