[HDRP] Squared artifacts for iridescent material when on top of Lit using Clear Coat



{color:#DE350B}*Read carefully the Additional infos. *
Repro steps :
- Open attached project
- Open scene called "Iridescence"
- Go to game view

Expected : Both sphere should look the same
Result : The sphere that is on top of the plane with clear coat has blocky artefacts

Additional infos :
- If you remove the normal map from the sphere, doesn't repro
- if you import the normal map used on the sphere properly (sRGB or as a Normal Map), it doesn't repro.
- It looks like this kind of issue that was fixed, so it might be related but another problem
- Lastly, since the issue only appears when a normal is not really properly imported, I'm not sure we need to spend a lot of time on this, just wondering if this is hiding a bigger issue.

Environment :
- Windows 10
- Unity 2023.1.0a21
- HDRP 15.0.1
