### Issue description

on beta 14, you cannot drag anymore a node from the scene tree to the script editor to get the node path or the ```@onready``` var snippet

### Steps to reproduce

Using beta 14, try to drag a node from the tree inside the script editor and see the arrow cursor turn into a circular white and red stop sign icon.

Note that this happens even if the script belongs to the currently opened scene.
