title: parent & child with position fixed, parent overflow:hidden bug
body: <p>I don't know if there is an issue, but I was wondering why the <code>overflow:hidden</code> does not function on <code>fixed</code> parent/children element.</p>
  
  <p>Here's an example:</p>
  
  <p><strong>CSS and HTML:</strong></p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.parent{
    position:fixed;
    overflow:hidden;
    width:300px;
    height:300px;
    background:#555;
  }
  .children{
    position:fixed;
    top:200px;
    left:200px;
    width:150px;
    height:150px;
    background:#333;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="parent"&gt;
    &lt;div class="children"&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
