Reproduction link or steps

1. Open https://stackblitz.com/edit/github-nci4o6nk-yfztxytw?file=rolldown.config.mjs,package.json,src%2Fread.js
2. pnpm i runs automatically
3. pnpm run build runs automatically
4. Run node src/index.js
5. Run node dist/index.js

What is expected?

node dist/index.js behaves the same with node src/index.js.
In other words, node dist/index.js outputs:

read foo
read foo

What is actually happening?

node dist/index.js behaves differently from node src/index.js.
In other words, node dist/index.js outputs:

read undefined

Any additional comments?

The plugin marks files other than index.js / setup.js as sideeffect free. If I do not mark read.js as sideeffect free, the output is correct. Even in that case, if I wrap globalThis.foo with a pure annotated IIFE, the output is wrong.

I think the missing limitation that should apply here is: "a side-effect-free module that may depend on a side-effectful module should not be reordered."
