Tested locally, it works as expected.

However, there's an issue: if you drag-and-drop onto an empty scene, a new inherited scene is created. This is intended engine behavior which only currently applies to the 2D editor. This operation doesn't care about the position you drag-and-dropped the scene in, so it shouldn't display the position and should display a message of this form instead:

Creating inherited scene from: filename.tscn

I think it's better to use the full path, because you can have multiple scenes with the same name in different folders. Also, if you just drag a sprite into an empty scene that will become the root.

Looks great!

That makes sense 🙂
