      The changes from c8e74f9 as part of SERVER-55723 were insufficient. An issue remains that this part of the future chain isn't being joined by the whenAll() / whenAllSettledOn() which comes later in the future chain. It is also possibe for chainCtx->oplogApplierConsistentButStaleFutures and chainCtx->oplogApplierStrictlyConsistentFutures to be reassigned while the whenAllSettledOn() are attempting to wait on them (read: data race).
