title: jQuery animation callback doesn't work
body: <p>Why doesn't it fire the alert?</p>
  
  <pre><code>var $anchor = $(this);
  
  $('.hide').val($(this).attr('href'));
  $('html, body').animate({
      scrollLeft: $($anchor.attr('href')).offset().left
  }, {
      queue: false,
      duration: 1000,
      easing: 'easeInOutCirc'
  }, function () {
      alert('test');
  });
  </code></pre>
