title: VueJS multiple mixins
body: <p>I have an error in my script I do not know to fix. I want to import multiple mixins I created.    </p>
  
  <pre><code>import GoogleMaps from '../mixins/GoogleMaps.js';
  import MFApi from '../mixins/MFApi.js';
  
      export default {
          template: require('../templates/map.html'),
          mixins: [GoogleMaps, MFApi],
  (...)
  </code></pre>
  
  <p>But this doesn't seem to work. How do I need to set the mixins variable properly if it is more than one?</p>
  
  <p>As soon as I add the new mixin to the variable, the first one is not recognized anymore.</p>
