XDomain doesn't give up waiting for an iframe to respond

The wiki says that timeout is the

Number of milliseconds until XDomains gives up waiting for an iframe to respond

The problem is that even if I set up timeout XDomains raises 'timeout' event and continues connecting. Here is my setup:

<script>//if xdomain.min.js emits timeout event we should check local storage
  xdomain.timeout = 1e3;
  xdomain.debug = true;
  xdomain.on('timeout', function (e) {
     //some code
  })</script>

Here is the browser console output:

xdomain.min.js:3 Mixed Content: The page at 'https://env-123.appengine.flow.ch/#/login' was loaded over HTTPS, but requested an insecure resource 'http://www.somesite.com/proxy.html'.

Looks like timeout is actually the "reconnect timeout"? How can I disable reconnecting all the time?

Thanks in advance!
