Panel Renderer component’s fields are not reset when resetting the component

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Create a new Panel Settings asset (Assets > Create > UI Toolkit > Panel Settings)
3. Select the "Assets/New Panel Settings.asset" asset in the Project window
4. Change Render Mode to "World Space" in the Inspector window
5. Create a new Panel Renderer GameObject in the Hierarchy window (Right-click > UI Toolkit > Panel Renderer)
6. Change any of the property fields under the World-Space Dimensions section in the Inspector window
7. Click the burger button for the Panel Renderer component
8. Click the "Reset" button
9. Observe the Panel Renderer component in the Inspector window

Actual results: The changed fields are not reset

Expected results: The changed fields are reset

Reproducible with versions: 6000.6.4f1, 6000.7.0b3, 7000.0.0a5

Can’t test with versions: 6000.0.0f1, 6000.0.84f1, 6000.3.25f1 (due to no Panel Renderer feature)

Tested on (OS): MacOS Silicon Tahoe 26.6.2

Notes:
