@JsonbPropertyOrder in relation to inherited properties clarification

in [JSONB specification document](https://jcp.org/en/jsr/detail?id=367) section 3.13, it is required that properties from parent classes are serialized first.

`@JsonbPropertyOrder` annotation is declared on a TYPE. Should it include properties from parent class and override statement from 3.13?

Given example:
```java
@JsonbPropertyOrder("b","a")
class A {
public String a;
public String b;
}

@JsonbPropertyOrder("c","d","a","b")
class B extends A {
public String c;
public String d;
}
```

What should be result of serialization instance of type B? Can the spec be clear on this behavior?

Start with section 3.13 of the JSON-B specification and compare it with the @JsonbPropertyOrder example in this issue. Review the related yasson issue 228, then document the expected serialization order and clarify whether inherited properties are included or overridden; no implementation file or test is identified.
