signalr: AutoReconnect currently broken in main branch code

I hope i don’t disturb the dev experience too much, but AutoReconnect does not work properly (48ff89d7)

When connected to any SignalR server everything is ok. As soon as the opposing server “dies”, the client will spam tons of error messages regarding reading from a closed websocket
