@benno5020 Thank you so much for this PR! Great work!

The remarks I have are only nitpicks and I'd be happy to fix these up myself when merging if you prefer (just let me know).

Thank you for the kind words! :)
When looking through the code again, I noticed that one test method's name and DocBlock were a little confusing so I changed it as well. See 755e941.

@benno5020 Thank you for making those updates. All good from me 👍🏻

If you don't mind, I'll reorganize the commits to be atomic again, force push and then I'll merge once the build has passed.

Agreed, that makes the description less confusing.
