Element get matchingTarget {
  if (_selector == null) {
    throw new UnsupportedError('Cannot call matchingTarget if this Event did'
        ' not arise as a result of event delegation.');
  }
  Element currentTarget = this.currentTarget;
  Element target = this.target;
  var matchedTarget;
  do {
    if (target.matches(_selector)) return target;
    target = target.parent;
  } while (target != null && target != currentTarget.parent);
  throw new StateError('No selector matched for populating matchedTarget.');
