Wrong packaging order with css

[joy-yu]

When I used manualChunksPlugin, I found that there was a problem with the css packaging order.

I have put import './styles/app-main.scss'; in the first line in main.ts.

In the final css packaging product, this part of css should be at the first. But that's not actually the case.

🤔 It seems like a vite bug, so I closed the issue here. vitejs/vite#6375
