Draggable Tree: renderDraggingNode / change cursor style

[arthur-FD]

Hello team,

I am trying to change the mouse cursor when I grab an item when using the Tree component. I am trying to use the renderDraggingNode but it does not seem to work as intended. The colour is changing as intended but the cursor is the same.
Also, it seems to add additional items hidden at the bottom of the html, I am not sur why - I cannot see this behaviour when I dont have this optional property.

Would you have any suggestion on how I should proceed to change the mouse cursor when grabbing an item?

Thanks!
Arthur
