Open the inspector and expend the materials.

Expected:  
The colorShader material should be excluded from serialization or reused after load.  
Referring to [BABYLON.ShaderMaterial#doNotSerialize](https://doc.babylonjs.com/typedoc/classes/BABYLON.ShaderMaterial#doNotSerialize)

Actual:  
The colorShader is serialized and loaded, and never reused again.
