SvelteKit2 + Vite 5 no longer gzip encodes when using vite preview

[HummingMind]

Describe the bug

SvelteKit2 + Vite 5 no longer gzip encodes when using vite preview. Used to work with SK1 and Vite4/Vite5. No longer works after upgrading to SK2.

The bytes transferred is over double what it should be, since there is no gzip compression for the JavaScript assets.

It's not an issue for production, but it is a DX issue for local development, as I always preview to get an idea on the bundle size of what would go "over-the-wire" in production.

  kit: {
    adapter: adapter({ precompress: true }),
  },

The precopress setting is in the config.

Thank you!

Reproduction

Set up a new SK2 project or migrate an existing project. Use the static adapter.
Build. Preview.
