Cookie not working in iFrame

Version

nuxt-i18n: 6.8.1
nuxt: ^2

Nuxt configuration

mode:

• universal
• [] spa

Reproduction Link

Steps to reproduce

Integrate nuxt website in an iFrame with a url to the non-default language.
Due to the lax cookie setting, the browser will block the cookie and somehow nuxt-i18n ignores the url and displays the default locale. Ironically this change is done after the asyncData hook, because the api requests are still done with the right Accept-Language header.

What is Expected?

Set the cookie also in cross origin cases to allow a safe iFrame integration.

What is actually happening?

The cookie is blocked on different domains
