Shiboken fails to detect polymorphic base class with a virtual destructor

class PolymorphicBaseClass {
public:
  PolymorphicBaseClass() = default;
  virtual ~PolymorphicBaseClass() = default;

  /* Workaround:
  virtual dummyMethodForShiboken() {
    Instead of having to write a lot of polymorphic-id-expressions,
    one can write a dummy virtual method in PolymorphicBaseClass.
    and shiboken sees it as polymorphic.
  }
  */

  void doSomething() {}
};

class InheritedClass : public PolymorphicBaseClass {
public:
  InheritedClass() = default;

  void doSomethingElse();
};
