Debug: "return Func()"-containing function ignored in debug stack

[GWRon]

SuperStrict
Framework Brl.StandardIO

Function Test1:Int()
	Print "hi"
	Test2()
End Function

Function Test2:Int()
	Return Test3()
End Function

Function Test3:Int()
	DebugStop
End Function

Test1()

Debugstack just lists "Test1()" and then "Test3()". Same happens if I extend Test2:Int() to do more.

But if I first of all fetch the result of the function call instead of straight returning it, then the debugstack is correct:

SuperStrict
Framework Brl.StandardIO

Function Test1:Int()
	Print "hi"
	Test2()
End Function

Function Test2:Int()
	Local res:Int = Test3()
	Return res
End Function

Function Test3:Int()
	DebugStop
End Function

Test1()
