Crash in FUniformExpressionSet::FillUniformBuffer trying access deleted UTextureCollection

Crash in FUniformExpressionSet::FillUniformBuffer trying access deleted UTextureCollection (Experimental in 5.6).

The licensee describes their crash, their analysis, and a proposed fix:
This crash is occurring because the UTextureCollection used by the material is being freed before the material. The material was already queued for renderering and tries to reference the now deleted UTextureCollection. FMaterialCachedExpressionData::AddReferencedObjects does not add references to ReferencedTextureCollections. Just need to add that call.

The proposed fix involves adding:
Collector.AddStableReferenceArray(&ReferencedTextureCollections);
to:
void FMaterialCachedExpressionData::AddReferencedObjects(FReferenceCollector& Collector)

They also mention they have made many changes to their code base to enable texture collection on 5.5 (the feature is experimental on 5.6), and noticed this oversight on the referred code.

There is no repro case, the issue was confirmed by code code inspection.

The issue is present on 5.5, 5.6, and 5.7 (CL42864112).

Inspect the code on \UnrealEngine\Engine\Source\Runtime\Engine\Private\Materials\MaterialCachedData.cpp#L73 (UE 5.5.4-Release)
There is no mention of ReferencedTextureCollections.
