Expected Behaviour

Any of

1. Invalid id error to be thrown. For example: non-external resolved id should be absolute path.
2. Failed to load error to be thrown. For example: id src/sub.js cannot be loaded by the default behavior of rollup as it's not relative path.
3. The module is not duplicated.

Actual Behaviour

The module ./src/sub.js is duplicated in the bundle.
