title: JQuery .popup("open") not working properly on iOS 9 device
body: <p>onClick event we call following</p>
  
  <ol>
  <li>$("#popupDialog").popup("open");</li>
  <li>$("#popupDialog").popup("open");</li>
  <li>$("#username").focus();</li>
  </ol>
  
  <p>the popup appears and suddenly disappear.</p>
  
  <p>We are facing this issue on iOS devices , since we updated ipad and iphone to ios 9 before iOS 9 it was OK.</p>
  
  <p>Mobile Application Platform : JQuery Mobile 1.4.2 using Mobilefirst 6.3 studio</p>
  
  <p>How can we fix this issue ?</p>
  
  <p>Thanks,</p>
