Properties window is not closed when the GameObject is deleted and the Properties window is not focused

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Right-click the "Main Camera" GameObject in the Hierarchy window
3. Click the "Properties..." button
4. Dock the Properties window together with the Game View
5. Click on the Game View to focus it
6. Delete the "Main Camera" GameObject in the Hierarchy window
7. Observe the docked Properties window

Actual results: The Properties window still exists in the Editor even when the GameObject is already deleted

Expected results: The Properties window is closed after the GameObject is deleted

Reproducible with versions: 2022.3.67f1, 6000.0.58f1, 6000.2.6f1, 6000.3.0b3, 6000.4.0a1

Tested on (OS): Ubuntu 24.04, macOS Silicon Sequoia 15.6.1

Notes:

• Does not reproduce if the Properties window is focused
• Clicking on the Properties window to focus it after reproduction makes the Properties window disappear
