If the sandbox exits, the container is still running. IMO, a periodic job is needed to check the status of sandbox.

If the sandbox container is stopped, the real container will lose the network but it will be still running. I am not sure what are the prefect way to represent this state. Perhaps leave the container as 'running' state makes sense because the container is actually running. However, I would let others to comment on it.
