title: mCustomScrollbar doesn't seem to work for horizontal scrollbars?
body: <p><a href="http://jsfiddle.net/3LQJG/2/" rel="nofollow">http://jsfiddle.net/3LQJG/2/</a></p>
  
  <p>Above is a JSFiddle demonstrating the problem. I invoke the <code>mCustomScrollbar</code> on the parent of the content holder which has <code>overflow</code> in the <code>x</code> direction. </p>
  
  <p>However, you will notice that it modifies the width of the container, and the scrollbar is inactive.</p>
  
  <p>How do I correct this?</p>
