title: Antd Form doesn't submit when there are more than one text input inside
body: <p>I have a simple example where for some reason form stops calling <code>onSubmit</code> callback if I add more than one text inputs and push 'Enter' key while one of the inputs is focused. </p>
  
  <p>Here is a link on CodePen: <a href="https://codepen.io/anon/pen/KePXOj?&amp;editors=001" rel="nofollow noreferrer">https://codepen.io/anon/pen/KePXOj?&amp;editors=001</a>.</p>
  
  <p>This one works:</p>
  
  <pre><code>&lt;Form onSubmit={(e)=&gt;{e.preventDefault(); console.log(e)}}&gt;
      &lt;Input/&gt;
  &lt;/Form&gt;
  </code></pre>
  
  <p>And this doesn't:</p>
  
  <pre><code>&lt;Form onSubmit={(e)=&gt;{e.preventDefault(); console.log(e)}}&gt;
      &lt;Input/&gt;
      &lt;Input/&gt;
  &lt;/Form&gt;
  </code></pre>
  
  <p>What am I doing wrong there?</p>
