What does this PR aim to accomplish?:

Per #1295 and this thread on discourse

Whilst technically "not our problem" it's simple enough to do and saves the occasional confusion when these two elements have no information in them.

Of course, we could also just change the names of the API properties, BUT that is more destructive to those that are using the API externally.

LGTM, not sure if there are other places that need the changes made, guess we'll find out!
