Fastboot compatibility is still an issue

Getting the following error compiling my app with ember-dragula using Ember 2.12 and the latest version of Fastboot.

ReferenceError: document is not defined

It looks like this is the offending code, but I don't see anything like it in the repo:

module.exports = useNative() ? NativeCustomEvent :

// IE >= 9
'function' === typeof document.createEvent ? function CustomEvent (type, params) {
  var e = document.createEvent('CustomEvent');
  if (params) {
    e.initCustomEvent(type, params.bubbles, params.cancelable, params.detail);
  } else {
    e.initCustomEvent(type, false, false, void 0);
  }
  return e;
} :

Added the library in ember-cli-build.js. Same issue pops up.

This appears to be a problem with the latest version of the library, not the addon.
