Expected Behaviour

When using preserveModules: true in a TypeScript project, all dependency should be resolvable in the output bundle.

Actual Behaviour

The output bundle contains lots of unresolvable tslib imports, such as:

import { __awaiter } from '../node_modules/tslib/tslib.es6.js';
import { __rest } from '../node_modules/tslib/tslib.es6.js';

The relative path ../node_modules/tslib doesn't exist in the output dir. If you add external: [/node_modules/] to rollup.config.js, the import path will be absolute, such as /home/user/xxx/.../node_modules/tslib/....

Config to Reproduction

// rollup.config.js
import typescript from '@rollup/plugin-typescript';

export default {
  input: 'src/main.ts',
  output: {
    dir: 'dist',
    format: 'es',
    preserveModules: true, // This setting triggers the bug
  },
  plugins: [typescript()],
};

// tsconfig.json
{
  "compilerOptions": {  "target": "es6"  }
}

How to bypass this bug

Copy the node_modules/tslib folder into dist manually.
