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

var instanceOrElement;
    if (shouldConstruct(Component)) {
      if (__DEV__) {
        if (this._debugID !== 0) {
          ReactInstrumentation.debugTool.onBeginLifeCycleTimer(
            this._debugID,
            'ctor'
          );
        }
      }
      instanceOrElement = new Component(publicProps, publicContext, ReactUpdateQueue);
      if (__DEV__) {
        if (this._debugID !== 0) {
          ReactInstrumentation.debugTool.onEndLifeCycleTimer(
            this._debugID,
            'ctor'
          );
        }
      }
    } else {
      
      
      if (__DEV__) {
        if (this._debugID !== 0) {
          ReactInstrumentation.debugTool.onBeginLifeCycleTimer(
            this._debugID,
            'render'
          );
        }
      }
