Typing of i18n.global.locale

[mberrg]

Reporting a bug?

I'm using vue-i18n 9.2.2, and the typing of 18n.global.locale is string, but is should be ComputedRef<string>?

My setup:

  const i18n = createI18n<[GlobalMessageSchema], SupportedLangs>({
    legacy: false,
    locale: defaultLang,
    fallbackLocale: 'en',
    messages,
  });
  console.log(i18n.global.locale);

Typing reported in VS-code of i18n.global.locale:
ts (property) VueI18n<{}, {}, {}, string, never, string, Composer<{}, {}, {}, string, never, string>>.locale: string

However the variable is clearly a computed ref (from console log):

ComputedRefImpl {dep: undefined, __v_isRef: true, __v_isReadonly: false, _dirty: true, _setter: ƒ, …}

Expected behavior

Typing of i18n.global.locale (and posisble others) should be a computed ref e.g.

(property) VueI18n<{}, {}, {}, string, never, string, Composer<{}, {}, {}, string, never, string>>.locale: ComputedRef<string>
