[Scala 3] Stepping into a method containing a single pattern matching

[adpi2]

def foo(x: List[Int]) = foo match
  case x :: y :: tail => ???
  case x :: Nil => ???
  case Nil =>   // <= step into foo stops here
     ???   

When stepping into a method that contains a single pattern matching, the debugger first stops on the last case. Why so? Is this a "bug" in the compiler? Should we skip it in the debugger?

Is it the same in Scala 2?
