title: jquery validate: focusCleanup: true and focusInvalid: false don't work as expected
body: <p>I am using Joern's <a href="http://bassistance.de/jquery-plugins/jquery-plugin-validation/" rel="nofollow noreferrer">jquery validation plugin</a> 1.6.</p>
  
  <p>My goal is to have the following behavior: remove the error message for an element once the user focuses it. From what I understand setting 'focusCleanup: true' should take care of this.</p>
  
  <p>However (at least on my browser (Firefox 3.5.7 on Linux)), I only get the desired behavior (ie, error message for a field disappearing once you focus it) if I <strong>click</strong> into the field; it doesn't handle <strong>tabbing</strong> into the field correctly.</p>
  
  <p>Sample code:</p>
  
  <p>HTML:</p>
  
  <pre><code>   &lt;form id='abc' name='abc'&gt;
      &lt;input type="text" id="t1" name="t1"/&gt;
      &lt;input type="text" id="t2" name="t2"/&gt;
      &lt;input type="submit" id="submit" value='submit'/&gt; 
      &lt;/form&gt;
  </code></pre>
  
  <p>JS:</p>
  
  <pre><code>   $("#abc").validate({
     focusCleanup: true,
     focusInvalid: false,
  
      rules: {t1: {required: true, email:true}, t2: {required: true,email:true}}
  });
  </code></pre>
  
  <p>I am setting 'focusInvalid: false' because the docs say one should avoid combining focusCleanup and focusInvalid; in my experience commenting out that line makes no difference.</p>
  
  <p>Am I doing something wrong? </p>
