URP Asset sub-assets show changes in sub-assets only after reimporting the URP Asset manually

Steps to reproduce:

1. Create and open new URP 3D template
2. Select any URP Asset file in the Project 
3. Add any Renderer Feature to the asset
4. Expand the sub-assets section on the URP Asset and observe

Actual results: Only the previously existing Renderer Feature is visible

Expected results: The added Renderer feature is visible in the sub-assets

Reproducible with versions: 2023.1.0a10, 6000.0.72f1, 6000.3.13f1, 6000.4.3f1, 6000.5.0b4, 6000.6.0a2

Tested on (OS): Windows 11 Pro (25H2)

Workaround: Reimport the URP Asset manually

Notes:

• This is just a visual bug, the Renderer Features work right when they're added to the URP Asset
