Running docker container has no ipAddress

[mesudip]

• This is a bug report
• This is a feature request
• I searched existing issues before opening this one

Expected behavior

Connecting a container to a network it's already connect should do nothing.

Actual behavior

It does something weird and removes the IPAddress of the container in that network.

• restarting the container solves the issue.

Steps to reproduce the behavior

sudip@Linux-Mint:~$ docker network create --driver overlay --attachable docker
sudip@Linux-Mint:~$ docker run -d --name docker alpine sleep 5m
sudip@Linux-Mint:~$ docker network connect docker docker
sudip@Linux-Mint:~$ docker container inspect docker | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "",
                    "IPAddress": "10.0.2.8",
sudip@Linux-Mint:~$ docker network connect docker docker
Error response from daemon: endpoint with name docker already exists in network docker
sudip@Linux-Mint:~$ docker container inspect docker | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "",
                    "IPAddress": "",
sudip@Linux-Mint:~$ docker restart docker
docker
sudip@Linux-Mint:~$ docker container inspect docker | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "",
                    "IPAddress": "10.0.2.8",
