Missing scripts warnings in HDRP Production Ready Shaders when entering Play Mode

Steps to reproduce:

1. Create a new HDRP project.
2. Window > Package Manager > Shader Graph >  Samples and import the Production Ready Shaders.
3. Open HDRPProductionReadyShaders scene and enter play mode.

Actual results: No issues.

Expected results: 14 console warnings about missing scripts.

Reproducible with versions: 6000.0.15f1, 6000.0.5f1, 2022.3.37f1

Can't test with versions: 6000.0.4f1 (17.0.3) & 2021.3, sample is not available.

Tested on (OS): Ubuntu 24.04

Notes:

• Does not occur in URP. (Tested in 6000.0.15f1)
• Would expect that you can navigate the scene in both HDRP and URP, this does not seem to be the case for either scene. In URP you can see the back of the scene, in HDRP you can only see the skybox.
