Research direction
Read the linked feature request in issue 8059 first to understand the intended polymorphism behavior. Reproduce the reported Kotlin generation case, then trace the generator behavior that creates a data class implementing another data class. Done means the generated Kotlin code no longer contains invalid data-class inheritance and compiles successfully.
