This PR aims to close #31320 (comment)
Basically we get the signal to revert to a block before our sync block during sync. In this case there is very little that we can do. We can just try to reorg back to the genesis or exit. It seems like exit is not a really good behavior since this can prevent nodes from syncing un-finalized networks.
