Material's color property value changes when changing material type in Properties view

Steps to reproduce:

• Create a 3D project
• Select Default Material
• In Properties view, change material's type from PrincipledMaterial to DefaultMaterial or SpecularGlossyMaterial
• -> warning about incompatible properties (baseColor) is shown
• Click OK
• -> Color changes
• In Material Editor, color is kept, although color property is a bit differently named in each material. See linked bug report for details.
