When New Brush is created with Cubmap texture under Paint Terrain causes the Editor to throw InvalidCastException, refer attached video.

Steps to repro:
1. Create a new project.
2. Project > Create > Sprite > Square
3. Inspector > Texture Type > Default
4. Inspector > Texture Shape > Cube > Apply
5. Hierarchy > Create > 3D Object > Terrain
6. Inspector > Terrain > Paint Terrain
7. New Brush > Assign Square(Cubmap)

Actual Result:
InvalidCastException thrown when the New Brush is created with Cubmap Texture

Expected Result:
New Brush is created with Cubmap Texture gracefully

Note: New Brush is introduced in Unity 2018.3
