When generating **child context** with a stateless Component, the context is not available to the children.

this._pendingCallbacks = null;
    this._pendingElement = null;
    
    
    this._context = null;
    this._rootNodeID = null;
    this._topLevelWrapper = null;
    
    
    
    ReactInstanceMap.remove(inst);
    
    
    
    
    
  },
  /**
   * Filters the context object to only contain keys specified in
   * `contextTypes`
   *
   * @param {object} context
   * @return {?object}
   * @private
   */
  _maskContext: function(context) {
    var Component = this._currentElement.type;
    var contextTypes = Component.contextTypes;
    if (!contextTypes) {
      return emptyObject;
