[ROS2] Using create_sub_node leads to two nodes with same name

If I create a node, and then create a subnode, I see on the cmd line 2 nodes with same name!
I think this is a bug, or is this not the correct usage?

If you then check params for the base node, it's coincidence which params will be shown, either that of base_node or from sub_node.

  //base_node and base_node/test are expected
  auto subnode = this->create_sub_node("test");

It looks like it is a bug (at least still present in October 2020):

Below, It is shown a possible workaround. You can just create a "full" new node extending the original node namespace (second parameter).

  auto subnode = rclcpp::Node::make_shared("test", parent_node->get_fully_qualified_name()));
