Loading a Material in WebGL breaks the lighting of the Material

As you can see in the video, I have 2 models they both use the same Material.
If I load the material you can see that the model on the right side has a different exposure.
This happens in the WebGL build. If I test it in the editor everything works fine.

This is the code that I use to load the material.

Code (CSharp):

1.  
2. [System.Serializable]
3. public class AssetReferenceMaterial : AssetReferenceT<Material> { }
4.  
5. public class LoadMaterial : MonoBehaviour
6. {
7.     public AssetReferenceMaterial AssetMaterial; //I use the same Material
8.     public Material Material; //I use the same Material
9.  
10.     public MeshRenderer MeshRenderer;
11.  
12.     //If I set te Material it looks normal
13.     public void SetMaterial()
14.     {
15.         MeshRenderer.material = Material;
16.     }
17.  
18.     //If I load the Material the lighting breaks of the material
19.     public void LoadAssetMaterial()
20.     {
21.         AssetMaterial.LoadAsset().Completed += OnLoadMaterialCompleted;
22.     }
23.  
24.     protected void OnLoadMaterialCompleted(IAsyncOperation<Material> mat)
25.     {
26.         MeshRenderer.material = mat.Result;
27.     }
28. }
29.
