title: twitter-bootstrap row-fluid doesn't adjust height according to it's child size
body: <p>I have the <a href="http://jsfiddle.net/rEsG2/" rel="nofollow">following</a> fiddle. It's essentially a </p>
  
  <pre><code>&lt;div class="row-fluid"&gt;
    &lt;div class="sidebar"&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I am just wondering why the <code>row-fluid</code> doesn't adjust the height based on the <code>sidebar</code> height? I can see the sidebar has a height of 1450px, so if all container div's by default adjust's to it's child div's size then it should also have a height of 1450px. If I check the height of the row-fluid, it stays at 0. How do I make this adjust accordingly?</p>
