Hello !
I face an issue with Intl on SSR.
When using new Intl.DisplayNames("en", { type: "region" }) and then console.log(regionNames.of("fr")) I get a different result on the server comparing to the client, as shown in the screenshot.
Note that it works as intended with the types language and currency.
You can test it yourself by cloning this repo : https://github.com/Kheuval/intl-reproduction
Thanks for your help !
