-from-tasty compilation fails on correct scala.js code

[pikinier20]

Compiler version

Newest master - c94b333
The bug occurs also on 3.1.0

Minimized code

import scala.scalajs.js

trait Foo[A] {
    def p: js.Promise[A] = ???
    def onFulfilled: js.Function1[A, Unit | js.Thenable[Unit]] = ???
    def onRejected: js.Function1[Any, Unit | scala.scalajs.js.Thenable[Unit]] = ???

    p.`then`[Unit](
    onFulfilled,
    js.defined(onRejected)
    )
}

Output

For command:
~/dotty/dist/target/pack/bin/scalac -scalajs -from-tasty target/scala-3.1.2-RC1-bin-SNAPSHOT/classes/Foo.tasty

Expectation

The same as for standard compilation which passes.

Does this also happen if you add scalajs-library_2.13 to the classpath?

[pikinier20]

No, it doesn't. So probably somehow the library is missing in classpath argument passed to Scaladoc

[pikinier20]

Okey, there's no bug. I realized that it might be related to sbt version since we've made some changes in scalacOptions resolution for doc task. The problem is gone on sbt 1.5.3+ since from this version the -scalajs flag is passed to Scaladoc.
