When you connect to a something using the /connect command it doesn't disconnect when you leave
Steps to reproduce:
1st. Make some sort of web socket server that uses the /connect command to interact with minecraft (eg. "Wilco's Realm Bot" to print the chat of a world)
2nd. connect to that server with wsserver or connect
3rd. leave the world and join another one
4th if you are using Wilco's Realm bot on discord and type something in the chat on that other world it will appear in the discord chat

What I expected to happen:

Minecraft would disconnect from that web socket server

What happened:

Minecraft stayed connected

NOTES:
If you are using a discord chat logger of some sort and you join a minecraft server it will log the chat anyway which could be un-expected
