title: Codename One UWP browser execute issue
body: <p>I am trying to obtain the HTML contents of a BrowserComponent in CodenameOne by using this code:</p>
  <pre><code>browserComponent.executeAndReturnString(&quot;document.documentElement.outerHTML&quot;)
  </code></pre>
  <p>This works in the simulator, on iOS and on Android. In a UWP app executeAndReturnString never returns. Here is a runnable example (use in the start method of a new project):</p>
  <pre><code>BrowserComponent browserComponent = new BrowserComponent();
  browserComponent.addWebEventListener(BrowserComponent.onLoad, evt -&gt; {
      Log.p(&quot;onLoad start&quot;, Log.INFO);
      Log.p(browserComponent.executeAndReturnString(&quot;document.documentElement.outerHTML&quot;), Log.INFO);
      Log.p(&quot;onLoad end&quot;, Log.INFO);
  });
  
  Form form = new Form(&quot;Browser Contents Test&quot;, new BorderLayout());
  form.add(BorderLayout.CENTER, browserComponent);
  form.show();
  
  browserComponent.setURL(&quot;http://www.codenameone.com&quot;);
  </code></pre>
  <p>In a UWP app this is everything in the log:</p>
  <pre><code>[EDT] 0:0:1,837 - Codename One revisions: 7dd4e7d08b3442d90959477ee52a5ae8c4361b29
   
  [EDT] 0:0:1,891 - onLoad start
  </code></pre>
  <p>I have tried the asynchronous BrowserComponent.execute methods and they do the same thing. Can anyone help me?</p>
