title: Have any browsers implemented the DOM3 EventListenerList?
body: <p>The answer was &quot;no&quot; back in March 2010:</p>
  <p><a href="https://stackoverflow.com/questions/2424737/browser-eventlistenerlist-implementation">Browser EventListenerList Implementation</a></p>
  <p>I'm wondering if there has been any progress since then.</p>
  <p>If the answer's still &quot;no&quot; ... any indication of when any browser might support it?</p>
