Scala JS source maps, map to CI runner dir?

[Quafadas]

In my pet project, vite complains about source map errors. I believe one of the culprits to be this sourcecode library.

Here's a sample .js.map file.

{
"version": 3,
"file": "frontend.Clients$.js",
"mappings": "blah blah",
"sources": ["https://raw.githubusercontent.com/raquo/Airstream/c769f6591e7f6f1377154d484ce8657b752aa179/src/main/scala/com/raquo/airstream/core/BaseObservable.scala", "file:///C:/temp/ilsclaims/frontend/src/utils.scala", "https://raw.githubusercontent.com/raquo/Airstream/c769f6591e7f6f1377154d484ce8657b752aa179/src/main/scala/com/raquo/airstream/state/Var.scala", "file:///home/runner/work/sourcecode/sourcecode/sourcecode/src/sourcecode/SourceContext.scala"],
"names": ["internal-b28b7af69320201d1cf206ebf28373980add1451", "eventClient", "internal-9fb50eb6088e86acde75de71513c77ec947f608e", "exposedEventClient", "notificationClient", "claimReportClient", "ilsopWrapperClient"],
"lineCount": 59
}

I think the important part, is the file:///home/runner/work/sourcecode/sourcecode/sourcecode/src/sourcecode/SourceContext.scala line, which obviously doesn't exist, in my local environment. Compared to the laminar source above, which references back to github.

I lurk discord, where this was discussed at some length;
https://discord.com/channels/632150470000902164/635668814956068864/1060561961810677760

Typelevel have a solution here,
https://github.com/typelevel/sbt-typelevel/blob/4da726ca021ea2c6459e8286d9ec49ab7c79a883/github/src/main/scala/org/typelevel/sbt/TypelevelScalaJSGitHubPlugin.scala#L35

And laminar / airstream must have one, as that appears to be working above.

I believe there to be a compiler flag, which could potentially point this back to this repository, for example. I will openly admit, that my understanding of this, is superficial however ...
