title: jQuery container height() not calculated properly
body: <p><code>$('.container').height();</code> gives the wrong value when it's child elements have spacing CSS attributes on it:</p>
  
  <pre><code>&lt;div class="container"&gt;
    &lt;div style="padding: 10px;"&gt;
        weiorng3poin4gr9p34ng9p34n5g934ng5o43ng534g
        &lt;div style="margin: 20px; "&gt;
           eiong349ng49ng934ng59p34n5g439g5
        &lt;/div&gt;
    &lt;/div&gt;
  
  &lt;/div&gt;
  </code></pre>
  
  <p>How can I get the correct height of <code>.container</code> ?</p>
