2D lights are rendered to overlay camera with no culling mask

I have an overlay camera set it's culling mask to only render some UI elements, but it renders 2D lights too, even with culling mask set to None. Is this the intended behavior of an overlay camera?

The result is that all lights are twice as bright, and I'm not sure if this is consistent on all platforms. It seems like a bug to me.

Also I'd like to hide gizmos for the overlay camera, but at least they are not visible if the ortho size is the same for both cameras.

 

bump. this is a major issue. devs please look into this

 

Can you confirm this still exists in the latest 2020.2 version? I haven’t had time to test it yet.
