title: reactjs is not compatible with ie 11 in some scenarios
body: <p>run <a href="https://github.com/reactjs/react-tutorial" rel="nofollow">https://github.com/reactjs/react-tutorial</a> in Chrome and Firefox, it works as expected. </p>
  
  <p>But in IE 11, after post a new comment, the new comment will flash for a second at the bottom, then it disappears. Refresh the browser window, the new comment does not show. </p>
  
  <p>When close all IE windows, and open a new process of IE, the new comment will show.</p>
  
  <p>Launch developer tools will also show the new comment.</p>
  
  <p>Also similar issue repro in <a href="https://github.com/i-like-robots/react-tube-tracker" rel="nofollow">https://github.com/i-like-robots/react-tube-tracker</a>.
  So it's not specific to the code.</p>
  
  <p>Repro in different machines. So it's not specific to machine configuration.</p>
