Intl.Listformat not being loaded for macOS Catalina Safari v14.1 and higher

See original GitHub issue

Type: BUG

What

Intl.ListFormat polyfill is not being loaded for Safari versions >= 14.1. I’ve observed that this feature is not available on macOS Catalina Safari V14.1 whereas it is available on macOS BigSur Safari V14.1

https://github.com/Financial-Times/polyfill-library/blob/master/polyfills/Intl/ListFormat/config.toml#L35

Details

  • Intl.ListFormat polyfill should be loaded for MacOS Catalina Safari v14.1 and higher
  • Try loading this polyfill.io link on macOS Catalina Safari v14.1 or higher. It says that polyfill is not needed for this browser whereas if we try to check the feature availability in the browser console, it’s undefined.
  • macOS version - 10.15.7
  • Safari Version - 14.1.2 (15611.3.10.1.5, 15611)
