// Analogous implementation for withReverseReferenceList, but contributions.
//
// This implementation uses a global cache (via WeakMap) to attempt to speed
// up subsequent similar accesses. Reverse contribution lists are the most
// costly in live-dev-server, but we intend to expand the impelemntation here
// to reverse reference lists in general later on.
