Short description of error
The "make local" button on the scene selection drop-down at the top of the UI does not actually convert the linked scene to a local scene.

Use the scene drop-down to select that scene.
Click the "make local" button.
Become disappointed.
workaround
Create a new scene that links all the objects from the linked scene using the + / Link Objects menu option. After that is done you can unlink the linked scene.
