Reproduction link or steps

1. Open https://stackblitz.com/edit/github-xv4yss-xwr4ef?file=src%2Fentry.js,package.json
2. npm i runs automatically
3. npm run build runs automatically
4. See dist/entry.js (not empty)
5. run npm run build:up to use rollup
6. See dist/entry.js (empty)

What is expected?

Builtin object constructors like new Map are treated as sideeffect free like rollup does and the output gets empty.

What is actually happening?

The output is not empty.

Any additional comments?

Found while trying to bundle Vite with Rolldown.

The code where rollup defines the sideeffects for each builtin functions / objects are written in https://github.com/sapphi-red/rollup/blob/master/src/ast/nodes/shared/knownGlobals.ts
