we have dev.our-root-domain.com in public DNS pointing to 127.0.0.1

I've run into resolvers that filter things like that to prevent dns rebinding attacks. And localhost (the hostname) does not work for CORS.

Best option is probably to set dev.our-root-domain.com in /etc/hosts

Haven't had an issue yet, with a team scattered across US, Canada and UK. I'm sure it's possible - but so far we've been using this for about 3 years with no hiccups.
Definitely more common on corporate networks.

I guess most home users (remote employees) are probably either using their ISP's resolvers, or browser DoH (Dns-Over-HTTPS).
