title: Render React into Shadow Root
body: <p>I am trying to encapsulate <strong>React Component in Shadow Root</strong>. The component is rendered without a problem, but <strong><em>events are not working</em></strong>. My code looks like this:</p>
  
  <pre><code>let shadow = document.getElementById('root').attachShadow({mode: 'open'});
  shadow.innerHTML = "&lt;div id='panel'&gt;&lt;/div&gt;";
  
  
  ReactDOM.render(
      &lt;Admin /&gt;,
      shadow.getElementById('panel')
  );
  </code></pre>
  
  <p>The version of React is 15.4.2.
  I went through the list of issues and can't understand if this is a React issue or I am doing something wrong.</p>
  
  <p>Any help will be appreciated! </p>
