title: Radio button's change event doesn't fire in WebKit when using keyboard for input
body: <p>Demo: <a href="http://jsfiddle.net/55ucw/1/" rel="nofollow noreferrer">http://jsfiddle.net/55ucw/1/</a></p>
  
  <p>In any browser other than Safari or Chrome, I can tab into a set of radio buttons and select one using the arrow keys and the change event will fire.</p>
  
  <p>In Safari or Chrome, I can tab into a radio group, and select a radio button with arrow keys, but the change event never fires. </p>
  
  <p>Am I missing something?</p>
