Rendering problems using flexbox in Firefox and Chrome 48
<p><strong>On chrome 47 (correct behavior):</strong>
On chrome 47, that div with <code>.scroll</code> is scrolling correctly, taking height 100% using flex.</p>

<p><strong>On firefox (wrong behavior):</strong>
While on firefox, that div with <code>.scroll</code> is using the content height and not scrolling properly.</p>

<p>What is the cross-browser solution to this problem?</p>

<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>for (var i = 0; i &lt; 100; i++)
  $(".scroll").append("Dynamic content&lt;br&gt;");</code></pre>

&lt;/div&gt;</code></pre>
