// Analogous implementation for withReverseReferenceList, for annotated
// references.
//
// Unlike withReverseContributionList, this composition is responsible for
// "flipping" the directionality of references: in a forward reference list,
// `thing` points to the thing being referenced, while here, it points to the
// referencing thing.
//
// This behavior can be customized to respect reference lists which are shaped
// differently than the default and/or to customize the reversed property and
// provide a less generic label than just "thing".
