Short description of error
[Please fill out a short description of the error here]

It happens when I try to toggle to Edit Mode on second scene if first scene has edit mode a object

Exact steps for others to reproduce the error

Open file
Select scene "Scene.001" and try to toggle to Edit Mode
Get a error

It is issue or planned (user) error? Getting the error don't full inform an user. Why the error happens? A user may be confused :)

P.S. For fix the error need in scene "Scene.002" to disable Edit Mode and than can be to switch to edit mode in "Scene.001"

Select scene "Scene.001" and try to toggle to Edit Mode
Get a error
Select scene "Scene.002", go to objectmode
Try to Select scene "Scene.001" again
