AnyVal case class of type alias fails with clashing generated bridge for apply

[rikvdkleij-cleverbase]

I see all kind of issues which have similar compilation errors but not for this case.

reproduction steps

using Scala (Scala 2.13.3),

    final case class Foo(bar: NonEmptySet[String]) extends AnyVal 

problem

bridge generated for member method apply: (bar: cats.data.NonEmptySetImpl.Type[String]): Foo in object Foo
which overrides method apply: (v1: T1): R in trait Function1
clashes with definition of the member itself;
both have erased type (v1: Object): Object
    final case class Foo(bar: NonEmptySet[String]) extends AnyVal

Expecting no compile error.

I've tried to override the apply method but that doesn't help.

minimized:

object Newtype {
  type Type[A]
}
final case class Fails(bar: Newtype.Type[String]) extends AnyVal

bridge generated for member method apply: (bar: Newtype.Type[String]): Fails in object Fails
which overrides method apply: (v1: T1): R in trait Function1
clashes with definition of the member itself;
both have erased type (v1: Object): Object

Looks like the backend doesn't dealias before determining if the apply method (synthetic or custom) requires a bridge method.

I got the same issue. This doesn't compile:

case class Foo(bar: AnyRef) extends AnyVal

but this compiles and runs fine:

case class Foo(bar: AnyRef) extends AnyVal
object Foo
