Reproduction steps:
1. Open the attached project “ReproProject”
2. Open the graph <Redacted> (more information can be found in internal notes)
3. Try to delete variable “PlayerStatus“ by right-clicking on it and selecting “Delete”
4. Observe the result

Actual result: No feedback is given to the user
Expected result: Feedback is given to the user (e.g. Error/Info message in the Console window, popup window)

Reproducible in: 1.0.12 (6000.3.11f1), 1.0.15 (6000.5.0a9)
Could not test with: 10.0.11 (unsolvable Unity Behavior package errors)

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Note: This behaviour is expected. The PlayerStatus variable cannot be deleted from the subgraph, as it's currently being used in the subgraph's representation settings
