(Case 1207484) Baked Global Illumination sections in Scene View doesn't work until baking lightmap

Hi, I found that the issue about lightmapping.

As title said, all view related to lightmapping information (SceneView’s Baked Global Illumination mode, Renderer’s Baked Lightmap section and so on) doesn’t work until you bake new lightmap in editor.

If you open the project which has already baked lightmap data, you can’t see any information about lightmap in SceneView’s Baked Global Illumination mode and Renderer inspector. Only Shaded mode shows baked status.

2019.3.0f4, 2019.2.17, 2019.2.10 has suffer from this issue.

It seems that current Unity’s lightmapping features are highly unstable.

(There are many other issue related to lightmapping, like this Editor crashes when calling Lightmapping.ClearLightingDataAsset() )

Also, Lighting is not updated when changing the active scene. It just gets fixed to the first scene loaded.
