Auxiliary Constructor in Generic Class with Type Bounds Error

Question

Can someone please explain why this code:

class Whole[T <: Comparable[T]](val name: T):
  val parts: mutable.Map[T, Part[T]] = mutable.LinkedHashMap()

class Part[T <: Comparable[T]](val whole: Whole[T], val name: T):
  //...
  def this(whole: Whole[T], part: Part[T]) =
    this(whole, part.name)
    //...

is giving the compiler error below on the line invoking the primary constructor this(whole, part.name)?

None of the overloaded alternatives of constructor Part in class Part with types
 [T <: Comparable[T]]
  (whole: Whole[T], part: Part[T]): Part[T]
 [T <: Comparable[T]]
  (whole: Whole[T], name: T): Part[T]
match arguments ((whole : Whole[T]), (part.name : T))
    this(whole, part.name)

How would I make this work?

I'm using Scala 3.2.1.

Everything is fine if I remove the type bounds...
