How to reproduce:
1. Open the attached “IN-149862” Project
2. In Assets->Scenes open the “testscene” Scene
3. Ensure that Hierarchy V2 is enabled
4. In the Hierarchy, expand everything in the “Editor world” section
5. Left-click on “Editor world” in the Hierarchy
6. Using the Down arrow key, navigate through the items until you reach the very bottom of the "Editor world" section
7. Observe the Inspector Window
Actual Result: The Hierarchy's selection highlight moves to the new Entity, but the Inspector displays nothing
Expected Result: The Inspector updates to show the newly selected Entity's components and data, same as with mouse selection
Reproducible with: 6000.5.0a7, 6000.5.7f1, 6000.6.0b7, 6000.7.0a4
Could not test with: 6000.0.81f1, 6000.3.0a1 (Hierarchy V2 is not available in these versions), 6000.5.0a6 (Editor World does not exist in Hierarchy)
Reproducible on: MacOS 26.5 (M1) , Windows 11 (By Reporter)
Not reproducible on: No other environments tested
Notes:
- Confirmed issue is isolated to keyboard-driven (arrow key) selection changes specifically; mouse-driven selection changes correctly trigger an Inspector update.
- The issue appears when “Editor World” was introduced into the Inspector
