CKB node sync pauses because connected peers’ heights are not the latest

Bug Report

Current Behavior

I am a Neuron wallet user and have been maintaining a CKB full node for a long time, meaning I regularly start the CKB node via Neuron to sync the block height. I’ve noticed that the block height stays at the latest height of the connected peers, but their heights are not the most recent. Restarting does not resolve this issue. Does CKB have a mechanism to ensure I connect to nodes with the latest heights for syncing data?

Expected Behavior

CKB node syncs to the latest, thus making Neuron usable.
