#5113) Previously, we were checking if the relay parent of a new candidate does not move backwards from the latest included on-chain candidate. This was fine prior to elastic scaling. We now need to also check that the relay parent progresses from the latest pending availability candidate, as well as check the progression within the candidate chain in the inherent data. Prospective-parachains is already doing this check but we should also add it in the runtime
