It looks like this PR has tripped your coverage threshold of 50%. I don't think this PR should be further tested though, as the bulk of the PR itself is additional tests that didn't already exist, rather than code that needs to be tested.

Yes, @alansaul, the coverage drop is a result of other changes. Seems the pipeline failed on this PR after to synching it with main. I'm going to address low coverage by a separate PR, so it should be fine to merge this one now.
Thanks again for your contribution!
