When the function ```validateAndDenormalize``` is called, the function ```getTypes``` would be called with the wrong class name.If you take a look at the ```getTypes``` function below, I'm not even sure if we still need the part of the discriminator at this place because we already passed the class name of the discriminated class.```    /**     *@return Type[]|null     */    private function getTypes(string $currentClass, string $attribute)    {        if (null === $this->propertyTypeExtractor) {            return null;        }        if (null !== $types = $this->propertyTypeExtractor->getTypes($currentClass, $attribute)) {            return $types;        }        if (null !== $this->classDiscriminatorResolver && null !== $discriminatorMapping = $this->classDiscriminatorResolver->getMappingForClass($currentClass)) {            if ($discriminatorMapping->getTypeProperty() === $attribute) {                return [                    new Type(Type::BUILTIN_TYPE_STRING),                ];            }            foreach ($discriminatorMapping->getTypesMapping() as $mappedClass) {                if (null !== $types = $this->propertyTypeExtractor->getTypes($mappedClass, $attribute)) {                    return $types;                }            }        }        return null;    }```Commits-------9fc56c7 [Serializer]: AbstractObjectNormalizer ignores the property types of discriminated classes
