/// @assertion Any post-feature library declaration which has a platform library
/// class marked base or final as a superinterface must be marked base, final or
/// sealed, and cannot be implemented locally, even if the superinterface chain
/// goes through a pre-feature library declaration, and even if that declaration
/// ignores the base modifier.
///
/// @description Checks that it is a compile-time error if a declaration from a
/// post-feature library is not marked `base`, `final` or `sealed` extends a
/// platform library class marked `final` and the superinterface chain goes
/// through a pre-feature library declaration
