Expected Behaviour

main.js without global imports

import { commonB } from './b.js';

function a() {
  console.log('function a');
  commonB();
}

export { a };

I tried different treeshake configurations, but the imports remained

Actual Behaviour

import to other entry or external lib;

import { commonB } from './b.js';
import './c.js';
import 'react-tooltip';

function a() {
  console.log('function a');
  commonB();
}

export { a };

See https://rollupjs.org/faqs/#why-do-additional-imports-turn-up-in-my-entry-chunks-when-code-splitting for an explanation,
output.hoistTransitiveImports is the option you are looking for.
