How to enable SASS sourcemaps in dev mode? PostCSS problem

[chupzzz]

Hello everyone. I don't know about your workflow, but I can't work without SASS sourcemaps in my VUE projects.

When I was used Vue + Vite + Quasar (as a plugin) - SASS sourcemaps worked just fine.
Now I'm trying to use Quasar CLI + Vite and it is a big trouble to enable sourcemaps.

I've enabled devSourcemap in quasar.config.js:

extendViteConf (viteConf) {
  viteConf.css = { devSourcemap: ctx.dev }
}

It helps for pure .sass files (app.sass, quasar.variables.sass, etc.) but don't do the job for my components SASS.

Seems like I found a problem, but can't find solution:

Styles in *.vue files (and all other style files) are piped through PostCSS by default, so you don’t need to use a specific loader for it.

Can anyone help me to disable PostCss in Quasar, please?
