STR:
1. Create a new project
2. Create a shader that uses shader_feature functionality.
3. Make a compilation error in the shader for a non-default variant of shader_feature
4. Assign this shader to a material, use the material on a cube in an empty scene
5. Make a custom build using C# and make sure to use BuildOptions.ShaderLivelinkSupport (https://docs.unity3d.com/2020.2/Documentation/ScriptReference/BuildOptions.ShaderLivelinkSupport.html)
6. Add a script to switch to a shader_feature with a shader that produces an error
7. Run the player

Expected: when switching to a variant that has compilation errors at runtime, error shader is used
Actual: nothing is rendered
