Thank you, @jacobfoard !
This is also a tiny PR... let me know if you would like me to do something similar to how we handled #1837, although I'm happy to wait for the full process.

@gmlewis That'd be swell. I made the fork for the org anticipating the PR to sit for a bit 😅, so thanks for exceeding expectations and being quick on the reply!
