  <p>Looking at the reference implementation, I've tried to do the same here: <a href="https://jsfiddle.net/gw3br69r/2/" rel="nofollow">https://jsfiddle.net/gw3br69r/2/</a></p>
  
  <p>I've tried listening to different events like <code>show</code>, <code>show:spinner</code>, <code>spinner</code>, <code>spinner:shown</code>, etc, and have also tried to listen to the event via <code>$on</code> detailed here: <a href="https://vuejs.org/api/#vm-on" rel="nofollow">https://vuejs.org/api/#vm-on</a> and <a href="https://vuejs.org/guide/components.html#Parent-Child-Communication" rel="nofollow">https://vuejs.org/guide/components.html#Parent-Child-Communication</a> but I'm unable to listen to that event. I have also tried the non minified debug build of vue.js, but I do not know of a way to track down all the events to see if <code>shown:spinner</code> is even getting called.</p>
