Steps to reproduce

visit the playground. It said 'Async component loader resolved to undefined. If you are using retry(), make sure to return its return value.'.

but if you download it to local and run, it works.

What is expected?

it should work online. Or a nicer tip should be provided if not possible to work.

What is actually happening?

it does not work online. And a confusing tip is provided.
