Short description of error
In a file containing multiples scenes, performing an undo in one of them makes the other ones "usersless".
Those scenes are then considered orphan and appear as such (0 prefix + red background) in the Scene list view.
Saving and reloading the file brings back scenes users, but the next undo will have the same effect.
This does not happen in 2.82a or with "Legacy Undo" enabled.
Exact steps for others to reproduce the error
- Open attached .blend file
- Both scenes have 1 user
- Move the cube in "Scene", then undo this operation
- "Scene2" now has 0 user
