The test name still says the parent may not be missing, not the root. Should this be a new test instead? Or do we just need to adjust the test's name?

Unfortunately no.
parent is the mandatory field. But without parent root is not determined.
Unfortunately root is checked first.
It is correct that a ValidationError occurs. However, the message is unfortunate.
Unfortunately, I have not found a better solution.
