Thanks @pmartindev! One suggestion, and I think it'd also be good to have a test here.

(If you don't feel like doing the test, just let me know and I'll commit it to your branch.)

Thanks @woodruffw! I'm happy to add the test with your guidance, or you can feel free to add it 😃 Are you looking for the same test you implemented in #17926 , or an additional test against the version?
