When assigning multiple materials to a renderer, the order they appear is different in the inspector than the material entries.

Repro steps:
1 Open attached project
2 Open "test" scene
3 Choose Main Camera in Hierarchy
4 Find Mesh Renderer in Inspector and notice that Material list(array) and List of Material's Objects(under Material list) has different order - see Capture.png

Expected results:
Materials in inspector should be in the same order as they appear in the material entries on the renderer component.

Actual results:
Materials appear in arbitrary order compared to the material entries on a renderer component.
