Reproduction

https://stackblitz.com/edit/repro-nuxt-i18n-aborted-navigation?file=app%2Fpages%2Findex.vue

Describe the bug

Nuxt i18n's default behavior of switching locales when navigating to a certain prefix unexpectedly also applies if said navigation has been aborted.

Additional context

Edit: I had to revert the fix below since the skipSettingLocaleOnNavigate flag had more side effects than I anticipated (e.g. no redirect to the correct locale when accessing the root of the app).

For my personal use case, I have for now fixed this behavior by setting the skipSettingLocaleOnNavigate flag and re-enable locale change manually. However, this is very likely not the expected behavior.

// Finalize pending locale changes after each navigation
const router = useRouter()
const i18n = useI18n()

router.afterEach(async (to, from, failure) => {
	if (failure) return
	await i18n.finalizePendingLocaleChange()
})
