[bug] TypeError: undefined is not a constructor (evaluating 'new Intl.Collator(void 0,{numeric:!0,sensitivity:"base"})')

Type: Bug report

What

I'm seeing this error reported by android devices, I'm guessing it's a device that doesn't support Intl.

Details

Expected behaviour:
Shouldn't be seeing this error.

Actual behaviour:
Browsers without Intl support are getting this error.

Hi @gkiely, could you please post the user-agents that you are seeing this error on as well as the full polyfill.io url you are using. With that information we can hopefully figure out what is going on.

@gkiely the polyfill.io url you are using does not include a locale to polyfill, that is likely the issue here. If you add Intl.~locale.en-GB or another locale name to the features parameter it should work :-)
