Blazor TreeView - DragAndDropEventArgs gives incorrect DroppedNodeData.Id when item is dropped into the root level

Question

I have following example of tree and registered event NodeDropped:

- A

- - B

- - - C

When I move item C to item A - args.DroppedNodeData.Id is A (It's OK) and list is changed to

- A

- - B

- - C

but when I move item C to root level (above or below) A - args.DroppedNodeData.Id is still A (It's wrong). Expected value is null because Dropped node is root not A

I am not able to recognize when is item moved to root level or root item.

Another problem is that args.DropLevel has original value

Could you help me please?
