title: window.openDialog does not work
body: <p>The app I am working on used windows.showModalDialog which depreciated, so I replaced it with window,.open which workd fine but with one issue - it is not modal. I have found that one can use window.open Dialog instead but replacing window.open with window.openDialog broke my links.</p>
  
  <p>I had </p>
  
  <pre><code>ret = window.open(target, "", "scrollbars=no,location=no,statusbar=no,menubar=no,resizable=no,width=500,height=300");
  </code></pre>
  
  <p>which worked, so I tried:</p>
  
  <pre><code>ret = window.openDialog(target, "", "scrollbars=no,location=no,statusbar=no,menubar=no,resizable=no,width=500,height=300");
  </code></pre>
  
  <p>which did not. Can someone help me fix it so it works?</p>
