Reproduction link or steps

1. Open https://stackblitz.com/edit/rolldown-rolldown-starter-stackblitz-3aeczjue?file=rolldown.config.mjs
2. pnpm i runs automatically
3. pnpm build runs automatically
4. Run pnpm build:up to see rollup's behavior

What is expected?

dist/after-preload-dynamic-hash.js to include the content of dist/entry.js, and dist/entry.js to have import './after-preload-dynamic-hash.js'.
In other words, output to be similar to Rollup's one.

What is actually happening?

dist/after-preload-dynamic-hash.js is empty.
