title: React event click not firing in Safari / IE
body: <p>I'm currently using React v0.14.0 and I'm not able to click on any links  generated by React on Safari v8.0.6 and IE. I've added cursor:pointer as suggested in this <a href="https://github.com/facebook/react/issues/1169" rel="nofollow">link</a> but no luck. The same code seems to work very well on Safari (Version 9.0.1 (11601.2.7.2)) without <code>cursor:pointer</code>. Can you please help me figure out how to make it work ?
  Below my code:</p>
  
  <pre><code>var React = require('react/addons');    
  var myComponent = React.createClass({
      displayName: 'helloworld',   
      render: function () {
          var style = {cursor : 'pointer'};
          return (
              &lt;p&gt;&lt;a onClick={() =&gt; alert('clicked')} style={ style }&gt;Hello World&lt;/a&gt;&lt;/p&gt;
          );
      }
  });
  module.exports = myComponent;
  </code></pre>
