showAlert() patch

[Simon Pieters]

Re http://krijnhoetmer.nl/irc-logs/whatwg/20120604#l-615
The script is inline in the spec. In the showAlert() function, just after  
the line:

       document.body.appendChild(currentAlert);

add:

       x.focus();


also change:

   window.addEventListener('keydown', function (event) {
     if (event.keyCode == 27) {
       if (currentAlert)
         closeAlert2();
     } else {
       closeAlert();
     }
   }, false);

to:

   window.addEventListener('keydown', function (event) {
     if (event.keyCode == 27) {
       if (currentAlert)
         closeAlert2();
     }
   }, false);


and remove:

   window.addEventListener('scroll', function (event) {
     closeAlert();
   }, false);


Thanks!
