I'm surprised the CI passes without the bracket. Should we care or ignore it?

To expand a bit: The point of a common formatting and linting ruleset is to not care about nitpicks in human code reviews. These discussions always slow down development. They can happen but on a per-ruleset basis not for each and every individual case.

Should we care about single-line brackets: Probably (main argument being diff noise here). But then we should change the rules globally.

I had this rule in mind: https://github.com/airbnb/javascript#blocks--braces. If we agree to enforce it globally (I thought we were), I will add it to a backlog of small changes. It's not really important, I think that it could be handled later, like a Friday later afternoon, to rest.
