CSS is not imported in output when component is only imported through virtual module

[NullVoxPopuli]

This is... 🙃

BUT, I have a custom rollup plugin which only imports components via virtual module

all components are basically bundled, and then exported:

// in a virtual file
export function myFun() {
  return {
    'key': () => import('./components/foo.gjs'),
  }
}

and then in a real file:

export { myFun } from 'virtual:wheee';

The <template></template> region is correctly transformed, but it looks like the CSS is lost (not present anywhere in dist)
