CSS source maps

[probablykasper]

Describe the problem

I'm not getting CSS source maps when using vite-plugin-svelte for Sass. I believe Vite supports CSS source maps now (vitejs/vite#649), so I'm guessing it's vite-plugin-svelte that doesn't support it?

The PR vitejs/vite#4880 that fixes vitejs/vite#649 has been reverted in vitejs/vite#4951 as it causes issues in other toolchains. The actual fix lives at vitejs/vite#4950, until that's merge, CSS sourcemaps will then work.

With that said, vite-plugin-svelte already handles sourcemaps well, so we'd need to wait for upstream.

Aah, makes sense

Since css sourcemaps is a general issue in Vite, I'm closing this in favour of vitejs/vite#2830.
