Wrong library dependency configuration for Scala.js

[adpi2]

Problem

The library dependencies of the fetchJS project are JVM artifacts:

> fetchJS / dependencyTree
[info] com.47deg:fetch_sjs1_2.13:1.3.1+44-b82a1d66+20201112-1442-SNAPSHOT [S]
[info]   +-org.scala-js:scalajs-library_2.13:1.3.0 [S]
[info]   +-org.typelevel:cats-effect_2.13:2.2.0 [S]
[info]     +-org.typelevel:cats-core_2.13:2.2.0 [S]
[info]       +-org.typelevel:cats-kernel_2.13:2.2.0 [S]

As we can see the cats-effect_2.13 is a JVM artifact and not a Scala.js artifact.
It should be cats-effect_sjs1_2.13 instead.

The fetchJS project can be compiled but it cannot be linked:

• the fetchJS / test are not executed
• no Scala.js main class using fetch can be executed

For instance, fetchJS / test does not run any test:

> fetchJS / test
[info] fetchJS / test completed

Or if I create a Scala.js project depending on fetch, it cannot be linked:

// project/plugin.sbt
addSbtPlugin("org.scala-js" % "sbt-scalajs" % "1.3.0")

// build.sbt
lazy val demo = project.in(file("."))
  .settings(
    scalaVersion := "2.13.3",
    libraryDependencies ++= Seq(
      "org.typelevel" %%% "cats-effect" % "2.2.0",
      "com.47deg" %%% "fetch" % "1.3.0"
    ),
    scalaJSUseMainModuleInitializer := true
  )
  .enablePlugins(ScalaJSPlugin)

// src/main/scala/Main.scala
import fetch._
import scala.concurrent._
import scala.concurrent.duration._

import cats._
import cats.effect._

object Main extends App {
  val executionContext: ExecutionContext = ExecutionContext.Implicits.global
  implicit val timer: Timer[IO] = IO.timer(executionContext)
  implicit val cs: ContextShift[IO] = IO.contextShift(executionContext)

  def fetch[F[_]: ConcurrentEffect]: Fetch[F, Int] =
    Fetch.pure[F, Int](42)

  Await.result(Fetch.run[IO](fetch).map(println).unsafeToFuture(), Duration.Inf)
}

Expectation

All library dependencies of the fetchJS project should be Scala.js dependencies:
