title: Wow.js is not working after using page loader
body: <p>I used wow.js to add some animations to my content to earn some time instead of using my own animations on .appear() </p>
  
  <p>Everything was working great until I had to use some kind of loader that hides the whole wrapper until the window loads. After doing that, the animations are already triggered when I'm scrolling the page. (It's a parallax page). Is this some kind of bug, or did I mess up?</p>
  
  <p>Here's the html and javascript:</p>
  
  <pre><code>&lt;img src="loading.gif" alt="" class="loading"/&gt;
  &lt;div class="MainWrapper" style="display: none"&gt;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>$('.MainWrapper').hide();
      new WOW().init();
  $(window).load(function() {
      $('.loading').hide(); 
      $('.MainWrapper').show(); 
  });
  </code></pre>
