This class is being used in both vector and minerva, and we are
currently depending on it working for our night mode rollout, so let's
add some test coverage! Also fixed a small spacing issue in production
code that was bothering me lol
Note: these are not totally exhaustive - next steps would be to ensure
that the exclusions/inclusions work with arrays and not only single
elements, but hopefully this helps build some confidence ☺️
