title: navigator.share is not working in a WebView
body: <p>Is there a reason why the <code>navigator.share()</code> JavaScript function is not working inside a WebView of my Android app? When accessing the same URL through the web browser, the native Android share dialog pops up, but not when accessing the URL from the WebView of my app.</p>
  
  <ul>
  <li>The URL is using https.</li>
  <li>The share action is user-triggered by an onClick.</li>
  <li><code>setJavaScriptEnabled</code> is set to <code>true</code>.</li>
  <li><code>setDomStorageEnabled</code> is also set to <code>true</code>.</li>
  </ul>
