Invalid CSS path in library mode

[mxvsh]

Versions

• vite-plugin-federation: 1.3.9
• vite: 6.0.5

Reproduction

https://github.com/mxvsh/vite-mfe-lib

Steps to reproduce

1. Install the dependencies in host and remote
2. Build the remote
3. Start host in dev mode

What is Expected?

It should be able to load the remote app along with its styles.

What is actually happening?

When I try to build the remote in library mode with "react" and "react-dom" externalized, then in the host app, the CSS won't get loaded, it points to an invalid URL. This is not the case with "normal" Vite + React application.

Q. How do we actually render the remote app (in host) built using library mode?
