title: Colorbox (jQuery) resize() not working in IE9
body: <p>I'm using Colorbox version 1.3.19 with jQuery 1.7.2 on IE9. I have the following code to set up my Colorbox:</p>
  
  <p>JS:</p>
  
  <pre><code>var colorbox_defaults =
  {
      iframe           : true,
      title            : false,
      innerWidth       : 500,
      innerHeight      : 325,
      slideshow        : false,
      slideshowStart   : "",
      slideshowStop    : "",
      current          : "",
      previous         : "",
      next             : "",
      close            : ""
  };
  
  $( "#my_link" ).colorbox( colorbox_defaults );
  </code></pre>
  
  <p>HTML: </p>
  
  <pre><code>&lt;a id="my_link" href="some_page.php"&gt;Click Here&lt;/a&gt;
  </code></pre>
  
  <p>After all the content is loaded on the page, I have this code that resizes the colorbox based on the height of the content of the page (data is filled in via AJAX requests, so the page is variable in length), like so:</p>
  
  <pre><code>var options = { innerHeight : $( 'html' ).height() };
  parent.$.fn.colorbox.resize( options );
  </code></pre>
  
  <p>This code works perfectly in both FF 12 and Chrome 18, but fails to resize in IE9. Any ideas why?</p>
