How to reproduce:
1. Open up user attached project
2. Add a Scene called 'main' to Hierarchy
3. Set up your Scene view so you could see the Canvas with text in front of you
4. Go to Play Mode and then navigate back to your Scene view
5. In Hierarchy try disabling visibility/pickability controls of DontDestroyOnLoad Scene

Expected result: Scene picker/visibility controls work as intended
Actual result: They don't work at all and clicking them does nothing
