Reproduction steps:

# Open “MaterialTest” project
# Select “New Material” in the Asset folder
# Note that in the Inspector user can change the Albedo (color) of the material
# In the Inspector for the “New Material” change Shader to Sprites/Default
# Observe the Inspector

Expected result: user can still change the color of the material
Actual result: user can’t change the color of the material

Reproducible with: 2021.3.7f1, 2021.3.13f1, 2022.1.22f1, 2022.2.0b14, 2023.1.0a17
Not reproducible: 2020.3.41f1, 2021.3.6f1

Note: in Sprites/Default shader the Albedo alternative would be called Tint. User can change color if the shader is reverted back to Standard
