repro: https://github.com/BlankParticle/rolldown-inlineDynamicImports-reprod

build the code with pnpm build, the output code in dist/index.js (//#region node_modules/.pnpm/[email protected]/node_modules/undici/index.js) will have module.exports.[module] code in global scope without the __CommonJS wrapper, which is invalid ESM code and causes node to crash

ideally undici code shouldn't even be in the bundle as it was a dynamic import in a function that was treeshaken out, so it has no use even with import side effects.

What is expected?

Ideally Undici code will be entirely treeshaken out
right now, it shouldnt produce invalid ESM code

What is actually happening?

Undici code is still in the bundle and invalid code is produced in build
