also pwa and icon modules don't work at all

The manifest at .output/server/chunks/app/client.manifest.mjs is not generated correctly, there is no css under entry-legacy.xxx.js entry.

This is in turn caused by .nuxt/dist/client/manifest.json not including css under .nuxt/client-legacy.js entry.

FWIW, I managed to fix the problem by the following pnpm patch patches/vite@3.1.8.patch:

                         : chunk.name;

With that, @vite/plugin-legacy starts injecting CSS into legacy chunks, which then makes its way into Nuxt/Nitro SSR bundle. I am not sure if that is a valid approach at all - it just happens to work.

If someone has time to come up with a minimal reproduction repo, please open an upstream issue.

I suspect the actual fix would be serving modern format scripts in addition to legacy (#15), and pull css information from modern format chunks.

[IlyaSemenov]

Note that upgrading vite to 3.2.x makes it work (thanks to vitejs/vite#10496), however it leads to FOUC because styles are inlined rather than injected via <link rel="stylesheet">. The patch above delivers better result.

Any news on this one? Running a new nuxt 2 + bridge build, it seems that global css styles aren't applied

#561 (comment) helps both with 3.1.x and 3.2.x
