title: jstree icon not aligned with element text
body: <p>I am using margin-top in CSS on the jstree as follows:</p>
  
  <pre><code>.jstree li a {
  color:rgb(80,80,80);
  font-size:130%;
  vertical-align:middle;
  margin-top:10px;
  }
  </code></pre>
  
  <p>However, the jstree expansion icon (right-pointing arrow) is aligned higher than the element as shown here: <a href="http://www.nicholaschase.com/jstree/test.html" rel="nofollow">from another question here</a></p>
  
  <p>How do I get the icon to align with the element text?</p>
