Importing a path-aliased JS module into a TS file does not correctly transpile on build.
Run npm run build to reproduce.
Observe working/ts importing working/js (a typescript file) via @/working/js. In dist/working/ts, it has correctly been transpiled to ./js
In notworking/ts, importing working/js (a javascript file) via @/notworking/js. In dist/notworking/ts, it has not been transpiled at all and remains @/notworking/js, throwing an error if ran.
