Reproduction

Run:

git clone https://github.com/sebj54/debug-nuxt-i18n
npm ci
npm run generate
npx serve .output/public

Describe the bug

When running the website in SPA mode (static files from npm run generate) :

• it is impossible to change the locale with switchLocalePath
• when you hit an URL prefixed with the locale, the default one is still used
• if you change the locale with setLocale, the locale is changed for $t but not for localePath

You can test the correct behavior in my reproduction by running npm run dev

Additional context

I tried @nuxtjs/i18n-edge and the bug also occurs with this version.
