Runtime java.lang.NoSuchMethodError when calling a method in anonymous class returning a mixin

[jchyb]

Compiler version

Scala 2: 2.13.15
Scala 3: 3.3.4

Minimized code

Compiled first with Scala 2:

object Scala2Objects {
  def obj =
    new Quasi {
      def become[T]: T with Quasi = ???
    }
}

trait Quasi {
  def become[T]: T with Quasi
}

Compiled second with Scala 3, depending on the above:

@main def main() =
  Scala2Objects.obj.become

Output

Exception in thread "sbt-bg-threads-63" java.lang.NoSuchMethodError: 'Quasi Quasi.become()'

Expectation

Not implemented exception

[som-snytt]

I recently noticed a ticket where Scala 2 omits a bridge that Scala 3 correctly implements.
