Sanity V3 Embedding System don't load styles

[Rychillie]

Earlier today I opened an Issue regarding about when use the new Sanity v3 embedding system with Sanity Plugin Markdown V3 the page crashes and it is not possible to run the Studio because Sanity markdown plugin is unable to find the react-mde CSS and apply it.

Error:

Global CSS cannot be imported from within node_modules.
Read more: https://nextjs.org/docs/messages/css-npm
Location: node_modules/sanity-plugin-markdown/lib/index.modern.js

However, I found that when I remove the css imports from the Markdown plugin module and add a call to my _app.tsx it is able to access Studio normally.

References:

Removing imports on node_modules:
~node_modules/sanity-plugin-markdown/lib/index.js file:

// require("react-mde/lib/styles/css/react-mde-all.css");

~node_modules/sanity-plugin-markdown/lib/index.modern.js file:

// import "react-mde/lib/styles/css/react-mde-all.css";

Add imports to css style:
./pages/_app.tsx file:

import type { AppProps } from 'next/app';
import "react-mde/lib/styles/css/react-mde-all.css"; // Add here
import '@/styles/globals.css';

export default function MyApp({ Component, pageProps }: AppProps) {
  return <Component {...pageProps} />;
}

My Studio page:
./pages/studio/[[...index]].tsx file:

import { StudioPageLayout } from "@sanity/next-studio-layout";
import { StudioProvider, StudioLayout } from "sanity";

import config from "../sanity.config";

export default function StudioPage() {
  return (
    <StudioPageLayout config={config}>
      <StudioProvider config={config}>
        <StudioLayout />
      </StudioProvider>
    </StudioPageLayout>
  );
}

My doubt/suggestion, does anyone know how we can implement this in the module?

I thought primarily of doing a PR with the removal request and adding a description in the README file explaining how to use it... But I don't find this productive at all, so I came after hours of research asking for help on how can we implement this?

I'm sure that for many users like me, this will already be a stepping stone to start using V3 and creating content with it!
