Panel Renderer UI elements reappear in the Game view when reselecting a disabled Panel Renderer GameObject

Steps to reproduce:

1. Create a new URP project
2. In the Hierarchy, right-click > UI Toolkit > Panel Renderer
3. In the Inspector, click "New" and open the created UI Document
4. Add any visible element to the UI Builder Hierarchy, for example a Button
5. Save and close UI Builder
6. In the Hierarchy, select the PanelRenderer GameObject and disable the GO
7. Select any other GO and reselect the PanelRenderer GO
8. Observe the Button reappears
9. Enter Play mode
10. Observe the Game view

Actual results: The Button reappears after reselecting the disabled Panel Renderer GameObject and remains visible in Play Mode even though the GameObject is inactive

Expected results: UI rendered by the Panel Renderer should remain hidden while the GameObject is disabled

Reproducible with versions: 6000.5.0a5, 6000.5.0b6, 6000.6.0a4

Can’t test with versions: 6000.4.5f1 (Panel Renderer not available)

Tested on (OS): macOS 26.4

Notes:

• The UI elements are not shown if the project is built
• Does not reproduce with legacy UI Document Component
