Namespaces include the node name where they previously appear to not do so

While reviewing this tutorial for ROS Lunar:

I noticed that the current rqt_graph rendering looks different than the historical screenshots in the wiki page. For example:

If I uncheck the namespaces option it looks like the screenshot currently on the wiki:

However, I feel that it should not require me doing that. That's why I think that the namespace is incorrectly including the node name at all times. Based on the code and rosnode info I do not believe these nodes are actually in namespaces:
