rspack in react app cannot resolve deep-imports from a monorepo library

[Nick-Lucas]

A common pattern with Nx is to have a library with its imports not in the main index.ts, this is achieved just by adding a glob path to tsconfig.json

"paths": {
  "@org/lib": ["libs/lib/src/index.ts"],
  "@org/lib/*": ["libs/lib/src/*"]
}

When using rspack though, this seems to not work, as it can't resolve the import:

// works
import { a } from "@org/lib";

// FIXME: this import fails at build-time as unresolvable
import { bar } from "@org/lib/test-import";

Minimal reproduction here, it's just 1 app 1 lib and 1 deep import: https://github.com/Nick-Lucas/nx-spack-import-repro
