`AnyRef` does not name a parent class of `Ref`

[noresttherein]

Reproduction steps

Scala version: 2.13.11

	class Ref extends AnyRef {
		override def clone :Ref = super[AnyRef].clone
	}

Problem

AnyRef does not name a parent class of class Ref
		override def clone :Ref = super[AnyRef].clone

Not much of an issue, since Object works, but still.
