name:short showing region abbreviations outside of USA chaotically

[nvkelso]

Regions are preferred at some zooms to source the text from name:short, but when we designed these 2 years ago that property was only on United States regions (states). Now we're seeing it in Indonesia, too, somewhat chaotically.

Either we need to limit to just USA labels (would need to be whitelist of short names since we don't have country codes?), or be less chaotic elsewhere.

Very Quick to find the issue here @nvkelso 👍
