(This was when it had the language scroll though, I think moving the extras to JS should have resolved that issue; maybe I was misremembering the details too.)
example.com is not a user-facing service. I don't want to disparage the designer, but it's not meant to be pretty. It's meant to be small so you can copy its response to an automated test or visually verify its correctness, or just out of the bandwidth consideration you'd still be serving it to billions of requestors, even if you insist it's not meant to be used that way.
