title: IE7 jquery selector returns "Failed"
body: <p>I've encountered a peculiar bug in IE7, all other browsers seem to execute this code just fine.</p>
  
  <p>What i'm trying to do is select the very first input/textarea on my page using this:</p>
  
  <pre><code>$('textarea.classname, input.classname[type=text]').first().focus();
  </code></pre>
  
  <p>This line returns the text "Failed".
  In IE7 my entire application fails after executing this line and I don't quite understand why.</p>
  
  <p>When I execute either one of the following lines it returns an empty jquery object which is what I'm expecting on the page I'm currently working on:</p>
  
  <pre><code>$('textarea.classname').first().focus();
  $('input.classname[type=text]').first().focus();
  </code></pre>
