Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Enable Hierarchy V2 in the Preferences window 
3. Install the Entities package (com.unity.entities)
4. Right click in the Hierarchy V2 window and create a new Sub Scene
5. Right click the new Sub Scene and select "Select Scene Asset"
6. Rename the Sub Scene Asset
7. Observe the Sub Scene in the Hierarchy V2 window

Actual results: The Sub Scene name is not updated

Expected results: The Sub Scene name is updated

Reproducible with versions: 6000.3.3f1, 6000.4.0b3, 6000.5.0a4

Can’t test with versions: 6000.0.65f1 (due to no Hierarchy V2 feature)

Tested on (OS): Ubuntu 24.04, MacOS Silicon Tahoe 26.1

Notes:

• Does not reproduce with the old Hierarchy window
