Next.js: Global CSS cannot be imported from within node_modules

[ryscheng]

I'm trying to create a React library using Plasmic components. This React library will then be published to npm and imported into a separate Next.js application.

Next.js does not support global CSS from node_modules, which prevents me from using the React library.
See:
vercel/next.js#19936

This is true if I use either the Headless API or Codegen in the React library.
I think it's because Plasmic components import the following file globally
https://github.com/plasmicapp/plasmic/blob/master/packages/react-web/src/styles/plasmic.css

Would it be difficult to move the necessary CSS somewhere else?
