Edit Custom Node Filename Bug

Dynamo in Revit 2023.1.1
Edit a custom node

Change something and save (Ctrl-s); the node name is changed to the same name as the graph it was in

Go back to Dynamo, and the new wrong node name is there

This can lead to node definition not found errors, etc.

Workaround: Only do Save-as and make sure it is overwriting the original file.
