When shapifying recursive instantiated types, the compiler ends up leaving the type as-is if it already has been a shape type. However, if both of type arguments are interfaces, and one of them is a recursive one, it ends up being shaped as-is, while the other is shaped to its underlying, causing mismatch in function signature. Fixing this by shapifying an interface type as-is, if it is fully instantiated and already been a shape type.
