'use client'

Hi, I'm the maintainer of [react-lenis](https://github.com/studio-freight/react-lenis) package and some people complain about using the library in next.js app context usage.
In fact it requires 'use client' directive on top of the file but I noticed that it's ignored by microbundle "Module level directives cause errors when bundled, 'use client' was ignored."
Do you have a solution for that ?

Start by reproducing the reported package usage in a Next.js app and inspect how Microbundle handles the module-level 'use client' directive during bundling. There are no files or tests named in the issue; done means the directive is preserved or otherwise supported without the reported warning.
