do you mind changing this too?

   // No page cache
 }
 
 onpopstate = function(e) {
-  if (!sessionStorage.beganTest) {
-      sessionStorage.beganTest = true; 
-      top.opener.windowLoaded();
-      return;
-  }
-  
   alert("onpopstate");
   top.opener.notifyDone(window == parent ? "FAIL" : "PASS");
 }
