Polymer paper-menu with Angular2
<p>I'm trying to user Polymer v1.0 elements with Angular2 beta3 and I'm having issues.  Some elements work fine, such as input boxes.</p>

<p>However, when I try and use paper-menu or paper-dropdown-menu it doesn't work.</p>

<p>How can I get this plnkr to work?</p>

      window.Polymer = window.Polymer || {};
      window.Polymer.dom = 'shadow';
    &lt;/script&gt;

    &lt;!-- 1. Load libraries --&gt;
    &lt;!-- IE required polyfills, in this exact order --&gt;

    &lt;!-- 2. Configure SystemJS --&gt;
    &lt;script&gt;
      System.config({
        transpiler: 'typescript', 
        typescriptOptions: { emitDecoratorMetadata: true }, 
        packages: {'app': {defaultExtension: 'ts'}} 
      });
      System.import('app/main')
            .then(null, console.error.bind(console));
    &lt;/script&gt;

  &lt;/head&gt;

  &lt;!-- 3. Display the application --&gt;
  &lt;body&gt;
    &lt;my-app&gt;Loading...&lt;/my-app&gt;
  &lt;/body&gt;
