Bug with locally referred assets from CSS

Referring to npm package with local assets with relative path resolution fails in newer Next.js versions. See issue #33781.

Working Locally (dev server)

Not working production

yarn build
yarn next start -p 4000
open http://localhost:4000

This is the URL generated by Webpack config:

But should be something like /_next/static/media/3A95AC_3_0.9adbdede.woff2
