title: First app_requests from FB.ui shows popup window on SSL with chrome
body: <p>When I try to send app_requests from a my app, everything is fine with firefox. (Both on HTTPS and on HTTP)
  But when the app is run from chrome, things work fine in HTTP (non-secure). But when it comes to HTTPS, instead of showing a lightbox (i.e. js generated dialog, on the same page), a new popup window is created and the lightbox is shown in that popup window.</p>
  
  <p>This causes the app to break (as popups are, by default, blocked by chrome and the user doesn't necessary click on allow popups from this website)</p>
  
  <p>Moreover, this happens only when the first request is made in an instance of app. When I click on the Invite button again, all the browsers show the lightbox modal (Even chrome)</p>
  
  <p>Here is the JS code used: </p>
  
  <pre><code>FB.ui({"method": 'apprequests',"message": "&lt;?=(INVITE_MESSAGE)?&gt;","title":"&lt;?=(INVITE_TITLE)?&gt;","to": user_ids)}, 
  function(response){if(response)info();}
  );
  </code></pre>
  
  <p>I am not using any special code (Either in PHP or JS) for my app (Somebody said I need to).
  The app is, on the whole built on PHP SDK from facebook.</p>
