Newly created GameObject is not highlighted and not unselectable when it is created while another GameObject is selected and Hierarchy V2 is used

Steps to reproduce:

1. Create a new Unity project using a 3D Universal Template
2. Go to Preferences > New Hierarchy
3. Make sure "Use new Hierarchy window" is enabled
4. Select any available GameObject in the Hierarchy
5. Right-click on the empty space below GameObjects in the Hierarchy
6. Select "Create Empty" and give it any name
7. Click on the empty space in the Hierarchy
8. Observe the Hierarchy and Inspector

Actual results: The created GameObject is not highlighted as selected in Hierarchy, but its properties are visible in the Inspector

Expected results: The created GameObject is highlighted or its properties are not shown in the Inspector

 

Reproducible with versions: 6000.3.5f1, 6000.4.0b6, 6000.5.0a4

Can’t test with versions: 6000.0.66f1 (Hierarchy V2 not available)

Tested on (OS): macOS 26.2 (M1)
