What is expected?
two.js and three.js should keep their named exports
import { __export } from "./_virtual/rolldown_runtime.js";
//#region three.ts
var three_exports = {};
__export(three_exports, { myVariable: () => myVariable });
const myVariable = "world";
//#endregion
export { myVariable, three_exports };What is actually happening?
two.js and three.js named exports are removed
import { __export } from "./_virtual/rolldown_runtime.js";
//#region three.ts
var three_exports = {};
__export(three_exports, { myVariable: () => myVariable });
const myVariable = "world";
//#endregion

If two.ts and three.ts are declared as inputs the exports are keep, but I would expect preserveModules not to remove any export.
Rollup reproduction, named export are preserved: https://bundler.sxzz.dev/#eNptkMFuwyAMhl/F8qXSFGV3pD3CrjtxoY3ZMhEcGVg7Rbx7naZNG7U3vt8/nxETejQT9rGjU5vTfI5o7tzgQZFOI0uGN3AJ8pHBCw9gsX1X0JZF7RGaLIVqg0t4U13phehHiB5UMz7IvAvpYrvmq+/GG+OBY8ow/H856d0+EHyo9MgSOos2bo3CIZSx1Su+/25/V/NTvtnQkXclZJhsBOCSx5LNAgCjUCL5o0/uSqBkYP6JZpl5lsFpdUdp2M1R1UHFqg/Zr0uxngG2+oDb
