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).

ReactDOM.render(
        <div>
          <div key="one">
            <div key="A">A</div><div key="B">B</div>
          </div>
          <div key="two">
            <div key="C">C</div><div key="D">D</div>
          </div>
        </div>,
        container
      );
      
      ReactDOM.render(
        <div>
          <div key="one">
            <div key="B">B</div><div key="A">A</div>
          </div>
          <div key="two">
            <div key="D">D</div><div key="C">C</div>
          </div>
        </div>,
        container
      );
      expect(container.textContent).toBe('BADC');
    });
  });
  describe('createOpenTagMarkup', function() {
    var genMarkup;
    function quoteRegexp(str) {
