Terrain paint functionality is disabled in second Inspector when you close initial Inspector



How to reproduce:
1. Create a new project
2. Create a Terrain (right-click in the Hierarchy tab -> 3D object -> Terrain)
3. Add one more Inspector tab (right-click on any tab -> Add Tab -> Inspector)
4. Notice that one inspector window has the Terrain Inspector disabled under the message "Inspector tab is a duplicate. Paint functionality disabled"
5. Close the functional inspector

Expected result: Terrain paint functionality is working
Actual result: Terrain paint functionality is disabled

Reproducible: 2018.3.0b7, 2018.3.3f1, 2019.1.0a14, 2019.2.0a1
Not reproducible: 2017.4.18f1, 2018.3.0b6, 2019.1.0a7 (terrain is editable with both inspectors)

- Terrain paint functionality is disabled, even when deleting or creating a new terrain

    Resolution Note (fix version 2018.4.1f1):

    The terrain may be deselected in the Hierarchy and then re-select for the new Inspector to be active.

    Have just created a New Project/scene - just basic terrain (but also added to VegetationStudioPro).
    Unity 2019.1.2f1 3D - Cannot edit terrain!
    Have this message in the inspector when selecting Terrain
    "Note: inspector tab is a duplicate. paint functionality disabled"

    This used to work...

    I have this in 2019.1.2f1. Not even using Window -> Layouts -> ... solves the problem. I didn't even add a new Inspector. All I did was load a scene and then this appeared. Terrain editing is now deactivated. Not even restarting Unity helps.

    I have this issue in 2018.3.8. Is this supposed to be fixed in .9 or .10? It’s not listed in the release notes.

    2018.3.6f1 and i also have the problem.
    Found that when i collapse the terrain component on all terrains and then open one, i can paint again.

    I have this issue without adding an additional inspector tab, I cannot edit terrain period due to the message being displayed and functionality disabled. Version 2018.3.6f1
