Losing websocket callback handlers when calling socketFor

[ramster-vinka]

Using SocketIO. I wonder if I'm using this correctly, but I'm losing callbacks in the actual socket object when socketFor is called during the socket is in disconnected state and the proxy object is updated with a new socket instance.

Initialize:

let socket = this.socketIOService.socketFor(url);
socket.on('myEvent', this.myHandler, this);

After this socket.listeners and socket.socket._callbacks contain all the added listeners.

Now if socket gets disconnected and I call again:
this.socketIOService.socketFor(url);

Inside socketFor function this.isWebSocketOpen(existingProxy.socket) is false -> new socket is created and set to existingProxy:
set(existingProxy, 'socket', newWebSocket);

After this socket.listeners contain added listeners, but socket.socket._callbacks does not. It only holds the default connecting and connect callbacks.

Is there something that I'm missing in the usage? Based on the examples socketFor seems to be a function that can be called several times. If I save the socket instance into a property and never call socketFor again, callbacks are working.
