Reconnection doesn't work

To reproduce the bug, visit http://jsbin.com/rebadowilo/1/edit?html,js,console without running the server. The following error is logged in the console:

Uncaught TypeError: Cannot read property 'close' of undefined
    at Object.o.close (cettia-browser.min.js:1)
    at Object.n (cettia-browser.min.js:1)
    at Object.e (cettia-browser.min.js:1)
    at u (cettia-browser.min.js:1)
    at Object.add (cettia-browser.min.js:1)
    at Object.i.on (cettia-browser.min.js:1)
    at Object.i.once (cettia-browser.min.js:1)
    at t (cettia-browser.min.js:1)
    at Object.<anonymous> (cettia-browser.min.js:1)
    at u (cettia-browser.min.js:1)

The expected behavior is to reconnect to the server.
