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).

ReactDOMComponent.Mixin = {
  /**
   * Generates root tag markup then recurses. This method has side effects and
   * is not idempotent.
   *
   * @internal
   * @param {ReactReconcileTransaction|ReactServerRenderingTransaction} transaction
   * @param {?ReactDOMComponent} the containing DOM component instance
   * @param {?object} info about the host container
   * @param {object} context
   * @return {string} The computed markup.
   */
  mountComponent: function(
    transaction,
    hostParent,
    hostContainerInfo,
    context
  ) {
    this._rootNodeID = globalIdCounter++;
    this._domID = hostContainerInfo._idCounter++;
    this._hostParent = hostParent;
    this._hostContainerInfo = hostContainerInfo;
    var props = this._currentElement.props;
    switch (this._tag) {
      case 'audio':
      case 'form':
      case 'iframe':
      case 'img':
      case 'link':
      case 'object':
