Headers are not send

[solodeveloping]

Describe the bug

I'm working an a browser extension, I'm using Vue + Vite for the web pages.

I needed to use OPFS, so I had to set Cross-Origin-Opener-Policy and Cross-Origin-Embedder-Policy.

I added this to the server, and it used to work.

It seems like it's not working anymore, the html file has it but other files don't.

I've checked this, but I'm not using preview #9864

I haven't seen any indication in the doc that the headers should not be always send, the doc is sparse though:

I have this config:

// in the plugins:
    {
      name: 'set-headers',
      configurePreviewServer(server) {
        server.middlewares.use((req, res, next) => {
          res.setHeader("Cross-Origin-Opener-Policy", "same-origin")
          res.setHeader("Cross-Origin-Embedder-Policy", "require-corp")
          next()
        })
      }
    }
  ],
  // WARN : necessary for wasm SQLite
  server: {
    headers: {
      'Cross-Origin-Opener-Policy': 'same-origin',
      'Cross-Origin-Embedder-Policy': 'require-corp',
    },
    watch: {
      ignored: [
        // "./src/options/worker.ts",
        // "./src/options/worker.js"
      ],
    },
  },
  optimizeDeps: {
    include: [
      'vue',
      '@vueuse/core',
      'webextension-polyfill',
    ],
    exclude: [
      'vue-demi',
      '@sqlite.org/sqlite-wasm',
      'quickjs-emscripten'
    ],
  },

Since then, I've updated a few files because I thought the error was from SQLite but it seems it was not.
