Jiri Daněk commented on DISPATCH-2079:
--------------------------------------

I've found two issues so far. I will have to compare with previous version to 
check if they are caused by deps update or if they were caused by other commits.

{code}
  on_reconnected = () => {
    const self = this;
    this.connection.once("disconnected", this.on_disconnected);
    setTimeout(self.on_connection_open, 100);
  };
{code}

The code this exception comes from was added for DISPATCH-1623.

Unrelated React warning, after clicking around the console for a while

{noformat}
index.js:1 Warning: Can't perform a React state update on an unmounted 
component. This is a no-op, but it indicates a memory leak in your application. 
To fix, cancel all subscriptions and asynchronous tasks in the 
componentWillUnmount method.
