Steps to reproduce:

1. Create a new 3D URP project
2. Create any new Shader Graph
3. Add any node (e.g. Custom Function) and select it
4. In the Graph Inspector, navigate to Node Settings tab
5. Modify anything, e.g. add list items to "Inputs" list
6. Click Ctrl+Z to undo
7. Observe the Graph Inspector

Actual results: The node gets unselected and its properties are no longer visible in the Graph Inspector

Expected results: The node remains selected and its properties are visible in the Graph Inspector

Reproducible with versions: 2023.1.0a4, 6000.0.75f1, 6000.3.15f1, 6000.4.7f1, 6000.5.0b8, 6000.6.0a5

Tested on (OS): Ubuntu 24.04, macOS 26.4

Note:

• Undo operation still gets successfully performed, but the loss of node state impacts usability
