Reset functionality doesn't work on "Emission" and "Motion Vector For Vertex Animation" in Material

Steps to Reproduce:

1. Open a new Project with HDRP Template
2. Window > Package Manager > ShaderGraph > Install
3. Create Assets > right-click > Shader > PBR Graph
4. Create Assets > right-click > Material
5. Assets > New Materia > Inspector > Shader > ShaderGraph > New ShaderGraph
6. Check option Emission = True
7. Check option Motion Vector For Vertex Animation = True
8. Cogwheel > Reset

Alternate reproduction steps:
1. Create/open a new Project using 3d template and Built in renderer.
2. Create a new default material using standard shader
3. toggle emission on
4. cogwheel/three dots > reset (results and "reproducible on" is the same for both reproduction paths)

Expected Result:
Emission and Motion Vector For Vertex Animation options set to the default value

Actual Result:
Emission and Motion Vector For Vertex Animation options does not set to the default value
