do you have a codesandbox?

[jeffal]

@longlho Here is a sandbox,

However, I've tried https://codesandbox.io/, https://codepen.io/, https://jsfiddle.net/ and https://stackblitz.com/. They all either do not run due to unrelated errors or do not support IE11.

Is there something else I can do?

@jeffal can you deploy your repro (with unminified version of dist) to a static website hosting service? For example, now.sh, surge,sh, or even GitHub pages?

@longlho Happy to take this one since I have access to BrowserStack.

@jeffal what do you use to polyfill Intl.PluralRules?

[jeffal]

@longlho @formatjs/intl-pluralrules v1.5.2 (using v.1.5.3 in the sandbox)

require('@formatjs/intl-pluralrules/polyfill');
require('@formatjs/intl-pluralrules/dist/locale-data/en');

@pyrocat101 Here an updated codesandbox and deployment:
