title: Css columns height incorrect in Safari only
body: <p>This code is working fine in Chrome/Firefox, but in Safari the content below my 3-column div is being pushed down much further than it should, as if the column content was condensed within a single column.</p>
  
  <p>This can be seen here: <a href="http://codepen.io/anon/pen/egxvqP" rel="nofollow noreferrer">http://codepen.io/anon/pen/egxvqP</a></p>

  <p>Relevant code:</p>
  
  <pre><code>.postIntro {
    width: 100%;
    display: inline-block;
    margin-top: 18px;
    column-count: 3;
    column-gap: 30px;
    column-fill: balance;
  }
  </code></pre>
