[Scene Graph] Material Overrides on prefabs work inconsistently

Summary

When overriding materials on a prefab within a scene, the materials do not display correctly within the edit session. Occasionally they will also revert to their default material upon editor restart.

We are using One File Per Entity - not sure if this affects the issue.

I raised a bunch of posts about prefab stuff they are all resetting.

Issue with SG prefabs resetting editable override values on any copy from a copy of the initial copy

Summary I will provide a video showing the issue but what seems to be happening is when you place the initial prefab and change any values then any copy from this original will save the override values and it’ll be fine. The issue seems to be from a copy of a copy of the original then any override value is reset to default ? This doesn’t seem intended as i would think any copy of any prefab would instantly create a copy of that prefab and its state ? Please select what you are reporting on: U…

I believe these are being looks at tho so they might fix this as part of it unsure if its related but sounds somewhat.
