Issue description

It is impossible to set a saved StandardMaterial3D to any Material slot in the editor (e.g. Surface of a mesh or the Surface Material Override in a MeshInstance3D). It will give the following error:

The selected resource (StandardMaterial3D) does not match any type expected for this property (BaseMaterial3D,ShaderMaterial).

The editor does not accept BaseMaterial3D subclasses it seems, only direct classes as specified in the error message.

Steps to reproduce

• Create a StandardMaterial3D and save it.
• Try Load or Quickload it into a material slot (same scene, different scene, does not matter)
• See the error message The selected resource (StandardMaterial3D) does not match any type expected for this property (BaseMaterial3D,ShaderMaterial) popup
