[Bug]: [OpenAPI3] Inconsistent constraints for generic type vs concrete type

[albertxavier100]

Describe the bug

In the example, B.x has constraint maxLength: 100 while BB.x has constraint maxLength: 1

e.g. Since BB use allOf and validation will pass the maxLength: 100 but when validating '#/components/schemas/AA', it will failed.

The constraint should be intersection.
The problem should caused by inline the properties from generic types. We use $ref for concrete types which doesn't produce the problem.

I am not sure this is wrong, I don't think the value on the property here should loosen the original restriction.
