This is a placeholder. I will update this once I've finished testing.

@frankdugan3 mix test outputs the following. I don't think it's related to my changes.

@frankdugan3 Am I running the tests correctly, or are they not something that need to pass in order for my PR to be merged?

I'm sure the failing test is a bug on my end, will merge it today as it LGTM if you take it out of draft mode.
