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).

var inst = this;
  ReactDOMOption.postMountWrapper(inst);
}
var setContentChildForInstrumentation = emptyFunction;
if (__DEV__) {
  setContentChildForInstrumentation = function(content) {
    var hasExistingContent = this._contentDebugID != null;
    var debugID = this._debugID;
    var contentDebugID = debugID + '#text';
    if (content == null) {
      if (hasExistingContent) {
        ReactInstrumentation.debugTool.onUnmountComponent(this._contentDebugID);
      }
      this._contentDebugID = null;
      return;
    }
    this._contentDebugID = contentDebugID;
    var text = '' + content;
    ReactInstrumentation.debugTool.onSetDisplayName(contentDebugID, '#text');
    ReactInstrumentation.debugTool.onSetParent(contentDebugID, debugID);
    ReactInstrumentation.debugTool.onSetText(contentDebugID, text);
    if (hasExistingContent) {
      ReactInstrumentation.debugTool.onBeforeUpdateComponent(contentDebugID, content);
      ReactInstrumentation.debugTool.onUpdateComponent(contentDebugID);
    } else {
      ReactInstrumentation.debugTool.onBeforeMountComponent(contentDebugID, content);
      ReactInstrumentation.debugTool.onMountComponent(contentDebugID);
