VueI18N attribute not found in app on production build

What happened?

I did an explanation over at vue-i18n-next as I thought it could be a vue-i18n error [https://github.com/intlify/vue-i18n-next/issues/1095]

The issue I'm facing is I have i18n on both the local project and app extension. App extension main goal is to combine the local project's i18n objects into the app extensions. I realised that __VUE_I18N__ is not in the app during production build which produces the error on my app extension. Surprisingly, the i18n on the local project still works as normal but I am unable to convert the i18n that is in the app extension.

What did you expect to happen?

No errors should be faced as what I see in development build.

Reproduction URL

NIL as it is an app extension

How to reproduce?

Try to access the app i18n which is configured in the local project using the app extension
