title: Span inside H2 tag not showing up
body: <p>I'm trying to add a span inside of an H2 tag that will show a caret for dropdown, but everything I try I can't get it to render. When I look in the developer console my span doesn't even show up. Looks like it's not even being rendered. Is there something in the H2 style that I need to override? I can't find it. </p>
  
  <p>HTML</p>
  
  <pre><code>&lt;h2 class="panel-title"&gt;Drilldown&lt;span style="float:right" class="down_caret" id="drilldown_caret"&gt;&lt;/span&gt;&lt;/h2&gt;
  </code></pre>
  
  <p>CSS for H2</p>
  
  <pre><code>.dashboard-row .dashboard-panel h2.panel-title {
      font-size: 20px;
      margin: 0;
      padding: 5px 55px 5px 10px;
      font-weight: 200;
      border-bottom: 1px dotted #ccc;
      white-space: nowrap;
      text-overflow: ellipsis;
      overflow: hidden;
  }
  h2, h3 {
      line-height: normal;
  }
  h2 {
      font-size: 27px;
  }
  h1, h2, h3 {
