Describe the bug

1. Ensure the Player Setting "Enable Theatre Mode by Default" is disabled.
   
2. Ensure the Distraction free Setting "Hide Recommended Videos" is enabled.
   
3. Go to any video without any other Sidebar items.
4. Ensure that the single column template is used.
5. Go back to settings and enable "Enable Theatre Mode by Default".
   
6. Go back to that same video.
7. See that Dual column mode is used despite there being no sidebar items.
   

Expected Behavior

When theatre mode is enabled by default it's adds the class useTheatreMode to the VideoLayout even when toggling theatre mode is impossible

The class useTheatreMode should either not be present or not overide the noSidebar class.
