az login device login

### Describe the bug

1. use the docker image mcr.microsoft.com/azure-cli on an virtual Box.
2. use docker exec -it sh to enter the container
3. az login

this initiates a device login access

4. the network connection of VM disappear.

stopping the container bring the connection back.

A ping to google.com while executing the above steps shows it:
