Latest issues
- An added cloned VisualTree is layered over other UI in a specific project build

- The shortcut character is typed into the name field when a [Shift + <any alphanumeric key>] shortcut is used to create the asset from "Asset/Create"
Resolution Note (fix version 2020.2):
When we are rendering material previews it's possible to exceed the limit of 63 that exists due to preview scene limitations. We need to be more careful about returning preview scenes after each render so they can be shared.
