Incorrect source map with SASS (and Windows) ?

[mistic100]

Hello,

There seems to be a problem when using this plugin with SASS loader

For this issue you can check the simple repro I created here https://github.com/mistic100/fluffy-octo-sniffle

The generated map is :

{
  "version": 3,
  "sources": [
    "dist\\main.scss"
  ],
  "names": [],
  "mappings": "AAAA;EACE,gBAAgB,EAAE",
  "file": "dist/index.css",
  "sourcesContent": [
    "body {\n  background: red; }\n"
  ]
}

The problems here are :

1. The "sources" is invalid, it does not reference the source files but a non-existent file
2. The "file" is invalid, it should be "index.css" without "dist/"
3. The "mappings" are not the one you'll get but running node-sass manually
4. There is apparently no reason "sourcesContent" is here

If you uncomment line 17 of rollup.config.js to configure the sassLoader with outFile : 'dist/index.css' the output is now :

{
  "version": 3,
  "sources": [
    "src\\scss\\main.scss",
    "src\\scss\\_vars.scss",
    "dist\\main.scss"
  ],
  "names": [],
  "mappings": "AAEA;EACE,gBCHS,EDIV;;AEDD,qCAAqC",
  "file": "dist/index.css"
}

1. The "mappings" are correct
2. The "file" is still wrong
3. The "sources" is a mixed version of the real source the same non-existent file
4. The "sources" should start with "../"
5. The "sources" use Windows path separators !!! (I am on Windows of course)

I hope I am being explict on the issue, please let me know if you need more info.
