Steps to reproduce:
- Create a new Unity project using the Universal 3D template
- Install the Visual Effect Graph package (com.unity.visualeffectgraph)
- Create a new Visual Effect Graph (Assets > Create > Visual Effects > Visual Effect Graph)
- Open the newly created Visual Effect Graph
- Create a new Category named "Attributes" by clicking the "+" button in the Blackboard
- Observe the Blackboard and the Console window
Actual results: The category name is reverted with no information given to the user as to why, but when naming a category to the same name another category exists with throws an informational error
Expected results: Informational error is thrown why the rename operation cannot be completed
