title: InfoPath 2013 web form doesn't open the browse dialog in the people picker control
body: <p>I have a user picker control, which when used in preview mode open a dialog to find users when I click on the browse button,
  but do nothing when deployed on the SharePoint server.
  If i type a user in the input box, the check names button is working and provide multiple choice when it's the case.
  As the people picker control was modified in the new SharePoint 2013, could it be a side effect ?
  Does anyone have the same problem ?</p>
