manualChunks is not working on 2.17.2

[kran6a]

Describe the bug

Recently I updated @sveltejs/kit from 2.16.1 to 2.17.2 on a website that used manualChunks to reduce the number of generated chunks and group code by concern.

The result is the following build:

Note that named chunks are on the server and hashed chunks on the client.

Reproduction

Run pnpm build and see the generated client chunks on .svelte-kit/output/client/_app/immutable/chunks
