Connected to two servers at once

I went to log in to one of the servers I play on but accidentally clicked another one so naturally I clicked cancel. I then went onto the other server and everything was weird. The two times were conflicting so the time was flashing every tick and I was receiving chat and title commands from both servers, tab, chucks, and sending chat went to the correct server but everything else was conflicting. Another weird thing that happened is one of the servers was hypixel and I wasn't moving on it so I was marked as AFK and it sent me to the AFK world which did work, but the chucks didn't load. I tried to recreate this but I couldn't get it to work so sorry about that.
