Editor lighting components not displaying correctly with diffuse off with lumen enabled

• Open any scene or create a new on and add a directional light and some basic shapes
• Be sure to have lumen enabled
• After that you can start to toggle the lighting components
• Try disabling everything and then only have “Direct lighting” enabled. You’ll notice that the screen stays black

• Instead, I would expect to see the direct lighting from the directional light.

Note this issue occurs only for Direct Lighting, Dynamic Shadows, and GI when the Diffuse is not active
