Reproduction link

https://gitlab.com/njam/repro-nuxt-html-lang

Steps to reproduce

1: Clone the repro repo:

git clone https://gitlab.com/njam/repro-nuxt-html-lang
cd repro-nuxt-html-lang

(relevant commit: https://gitlab.com/njam/repro-nuxt-html-lang/-/commit/be48fd82f0fdfd8197dbf7870a4cb9d74778a09f)

2: Build the static files, and serve them

yarn install
yarn run generate
npx serve ./dist

3: Open the page in the browser: http://localhost:5000

What is expected ?

The browser redirects to "/foo", and the html-tag has the attribute lang="de"

What is actually happening?

The browser redirects to "/foo", and the html-tag has the attribute lang="de de"

Open the browser's dev tools to inspec the "lang" attribute:

Additional comments?

Maybe vue-meta cannot correctly detect that the previous "lang"-value is coming from a server-rendered file when redirecting?
