Immutable Render Pipeline asset modification warning appears when saving a scene immediately after script recompilation

Steps to Reproduce:

1. Create a new Universal 3D project
2. Create a new MonoBehaviour script, make any change, and save it to trigger recompilation
3. As soon as compilation finishes, right-click in the Hierarchy and create an empty GameObject
4. Immediately save the scene using Ctrl+S or File > Save
5. Observe the Console

Actual Result: A warning appears stating that an internal Render Pipeline asset in an immutable package was unexpectedly modified during the scene save
Expected Result: The scene is saved without warnings about modified package assets
