title: Fix the Flex display in Edge
body: <p>I have the following: </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>.flex { display: flex; }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"
                                                                      rel="stylesheet"/&gt;
  &lt;div class="flex"&gt;
    &lt;input class="form-control" /&gt;
    &lt;div class="flex"&gt;
      &lt;input class="form-control" value="123456789" /&gt;
      &lt;input class="form-control" value="123456789" /&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Why I can't see the latest input entirely in Microsoft Edge (is OK even in IE), and how to fix it.</p>
