A class can inherit two declarations that are compatible from the overridability standpoint and are therefore combined to a non-trivial intersection. At the same time, the class can declare a member declaration that only overrides one of the intersection's members. In this case, we break up the intersection and only add the overridden parts to the declared member's direct overridden list. If the class doesn't override the intersection, it exists as intersection override, like before. #KT-65487 Fixed
