title: Flexbox and absolute positioning not working in Chrome and Safari
body: <p>I have a button class with the following styles:</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.button {
    align-items: center;
    background-color: #fff;
    border: 2px solid;
    border-color: #f48120;
    color: #f48120;
    cursor: pointer;
    display: inline-flex;
    font-size: 20px;
    font-weight: bold;
    justify-content: center;
    margin-bottom: 5px;
    padding: 3px 10px;
    position: relative;
    text-transform: lowercase;
  }
  
  .button::after {
    background-color: #fff;
    bottom: -4px;
    content: '\f111';
    display: flex;
    font-family: 'FontAwesome';
    font-size: 5px;
    justify-content: center;
    position: absolute;
    width: 25%;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;button class="button"&gt;Enviar&lt;/button&gt;</code></pre>
  </div>
  </div>
  </p>
  <p>If I uncheck and then check again the &quot;position: absolute&quot;  attribute in the inspector, the circle gets aligned in the center. Is this a Blink/Webkit bug?</p>
