When I rerender a component with "defaultChecked" or "defaultValue" react fails to update the "value" and "checked" attribute accordingly.

Before you say "use a controlled input" I would argue that this is a bug as it basically disallows uncontrolled forms with "reset" buttons. (It will always reset to whatever the initial default value was).

expect(
        EventPluginHub.getListener(inst, 'onClick')
      ).toBe(callback);
      expect(rootNode).toBe(ReactDOM.findDOMNode(instance));
      ReactDOM.unmountComponentAtNode(container);
      expect(
        EventPluginHub.getListener(inst, 'onClick')
      ).toBe(undefined);
    });
    it('should clean up input value tracking', function() {
      var container = document.createElement('div');
      var node = ReactDOM.render(<input type="text" defaultValue="foo"/>, container);
      var tracker = inputValueTracking._getTrackerFromNode(node);
      spyOn(tracker, 'stopTracking');
      ReactDOM.unmountComponentAtNode(container);
      expect(tracker.stopTracking.calls.length).toBe(1);
    });
    it('should clean up input textarea tracking', function() {
      var container = document.createElement('div');
      var node = ReactDOM.render(<textarea defaultValue="foo"/>, container);
      var tracker = inputValueTracking._getTrackerFromNode(node);
      spyOn(tracker, 'stopTracking');
      ReactDOM.unmountComponentAtNode(container);
      expect(tracker.stopTracking.calls.length).toBe(1);
    });
    it('unmounts children before unsetting DOM node info', function() {
      var Inner = React.createClass({
        render: function() {
          return <span />;
        },
