how bout a polyfill?

(function () {
      function CustomEvent ( event, params ) {
        params = params || { bubbles: false, cancelable: false, detail: undefined };
        var evt = document.createEvent( 'CustomEvent' );
        evt.initCustomEvent( event, params.bubbles, params.cancelable, params.detail );
        return evt;
      };

      CustomEvent.prototype = window.Event.prototype;
      window.CustomEvent = CustomEvent;
    })();

its taken from MDN, which seems to be currently down. https://developer.mozilla.org/de/docs/Web/API/CustomEvent

I think we need to polyfill the CustomEvent ctor in IE. I remember seeing one inlined in one of the other projects, but I'm having a hard time finding it...

I thought we already had this polyfill in the framework...let me check.

In the framework library we have this:

if (!window.CustomEvent || typeof window.CustomEvent !== 'function') {
  var CustomEvent = function(event, params) {
    var params = params || {
      bubbles: false,
      cancelable: false,
      detail: undefined
    };

    var evt = document.createEvent("CustomEvent");
    evt.initCustomEvent(event, params.bubbles, params.cancelable, params.detail);
    return evt;
  };

  CustomEvent.prototype = window.Event.prototype;
  window.CustomEvent = CustomEvent;
}

Should I be polyfilling it in aurelia-breeze for the purposes of testing?
