Nice Job! I added a couple of suggestions

[mrsarm]

The suggestions were applied. @mrjones-plip could you please review? ( @latin-panda is taking time-off for a few days).

[mrjones-plip]

@mrsarm - Sorry, I didn't get to this today. I'll grab it my Monday if @latin-panda hasn't already grabbed it already on her Monday (my Sunday ;) !

[mrjones-plip]

@mrsarm:

• sorry 1x b/c I see that @latin-panda is indeed out until later this week. My mistake!
• sorry 2x b/c I don't think I can tend to this PR well enough in the time given. I kinda escaped learning both node and core well enough to make this as easy as it should be 😅

[mrsarm]

Don't worry @mrjones-plip , I can wait for @latin-panda return , no urgency . Thanks !

[latin-panda]

Nice job, thanks for waiting, I left few minor questions in line

Nice LGTM!
It'd be nice to have the other it(....) cases to use the same label style: should do .... when .... so more uniform, otherwise good to go to AT!
Thanks

Needed to re-run CI again because flaky tests so did the grammatical changes as well.

Thanks!
