title: Copy to clip board from WebView
body: <p>In an UWP App with a WebView control the user can:</p>
  
  <ol>
  <li>Select some text from the loaded html</li>
  <li>Right-click</li>
  <li>Choose "Copy"</li>
  </ol>
  
  <p>However, choosing "Copy" does not copy the text? </p>
  
  <p>What is missing? Some code to handle the "copy event", or...?</p>
