Stubs: a class lists only one of its Kotlin supertypes (Arrangement.HorizontalOrVertical) #71

In the Compose stubs (develop fa2558e, run 37098191598) Arrangement.HorizontalOrVertical is rendered class HorizontalOrVertical(Horizontal), but in Kotlin it implements both Arrangement.Horizontal and Arrangement.Vertical. mypy then rejects Column(verticalArrangement=Arrangement.SpaceBetween) (a Vertical slot), and pythonx-compose has to annotate SpaceBetween, Center, spacedBy's return etc. as Any.

Completion: a stub renders every Kotlin supertype that has a stub class as a base (class HorizontalOrVertical(Horizontal, Vertical)), in an MRO-valid order; a plugin stub test pins it; tools/stubs/consumer.py gains Column(verticalArrangement=Arrangement.SpaceBetween, content=...) and Row(horizontalArrangement=Arrangement.SpaceBetween, ...) checked by check-stubs.sh (red on today's stubs).
