System Information
Operating system: Windows 10 Pro
Graphics card: GTX 1060 6 GB

Blender Version
Broken: 2.90.0, 2.83 (all)
Worked: (newest version of Blender that worked as expected)

Short description of error

Blender allows a linked copy of a scene to be created; this can be useful for compositing (one scene copy for Eevee, one for Cycles, with compositing).

Unfortunately, even though the GUI indicates the scene copies are linked, changing the active camera in either the original or the linked copy will not update the active camera in the other scenes. This leads to problems when rendering.

Exact steps for others to reproduce the error
Load the attached blend file.
There are two scenes. Scene.001 is a linked copy of Scene.
In the world properties for Scene, change the Scene Camera from Camera to Camera.001.
Change to Scene.001. The active camera is still Camera.

When you add a Linked Copy scene, this only means you link in the collections from the source scene and such, it is not the scene that is linked it self, just the contents.
(Why would you even want such a thing as a "linked" scene? There is no such thing if I am not mistaken)

The camera is a scene property and if you have a different scene [in your file you have Scene and Scene.001], each one can have its own camera.
Dont see a bug here, closing.
(feel free to comment again though if this is some kind of misunderstanding)

Fundamentally, what I'd like to do is to link the camera and render properties between scene copies. I'd hoped the 'linked copy' did this; hadn't realized it was collections-only at the time. There doesn't seem to be a way to set up drivers to tie scene camera, etc. together across scenes, though.
