Reproduction link or steps

I've read in some issues that rolldown has different behavior on purpose, so maybe this is not a bug at all. This is the only case I found in my codebase that has a different behavior so I thought I'd file it anyway.

• Clone https://github.com/lazka/rolldown-import-test
• npm install
• npm run rollup and npm run rolldown and compare the output

What is expected?

The output to be the same for

import TypesenseInstantSearchAdapter from 'typesense-instantsearch-adapter';

console.log(TypesenseInstantSearchAdapter);

What is actually happening?

• Rollup imports the default export
• Rolldown imports the namespace

System Info

rolldown v1.0.0-beta.42, see the package.json for other versions.

Any additional comments?
