title: Textarea placeholder isn't shown in IE 11 being rendered using React
body: <p>I have following HTML:</p>
  
  <pre><code>&lt;textarea placeholder="Usual textarea placeholder"&gt;&lt;/textarea&gt;
  &lt;div id="react-container"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>... and following JS:</p>
  
  <pre><code>ReactDOM.render(
      &lt;textarea placeholder="React textarea placeholder"/&gt;,
      document.getElementById('react-container')
  );
  </code></pre>
  
  <p>So, I am trying to show the same things using React and using usual HTML.</p>
  
  <p>However, in IE 11 at least, textarea rendered using React behaves like this:</p>
  
  <p><a href="https://i.stack.imgur.com/KFUrT.png" rel="noreferrer"><img src="https://i.stack.imgur.com/KFUrT.png" alt="enter image description here"></a></p>
  
  <p>So, textarea placeholder isn't displayed when page loaded. What's going on here? Both these textareas looks exactly the same in DOM.</p>
