Reproduction

https://stackblitz.com/edit/nuxt-starter-dx8kkg?file=nuxt.config.ts

The reproduction will not work on stackblitz due to using the custom domains. Please clone it & test locally.

Describe the bug

The documentation says:

Alternatively, to avoid the need for multiple builds, the locale domains can be overridden via runtime environment variables. The variable name should follow the format NUXT_PUBLIC_I18N_LOCALES_{locale code}_DOMAIN

However, based on my testing, this doesn't seem to work. The domains provided through .env do appear in the lang switcher (result of switchLocalePath() call), however, they don't switch the locale.

I'm not sure if I'm just doing something wrong or if this is a bug, but regardless, this issue either needs fixing or the documentation needs to be updated. I'd be happy to update the docs if necessary.
