Bug report

Hi guys, when I use dev: false inside my app, material-ui classes wont load.

Describe the bug

That's the code:

const port = process.env.PORT || 3000;
const dev = process.env.NODE_ENV !== 'production';
const app = next({ dev: false });
const handle = app.getRequestHandler();

app.prepare().then(() => {
	const server = express();
    
	// Routes and stuff...
})

The expected result should be:

Duplicate of #5892, this is not a Next.js issue.
