Gateway reconciler retries immediately instead of sleeping for 20 sec then retry, when the gateway haven’t yet changed to its desired state

Gateway reconciler retries immediately instead of sleeping for 20 sec then retry, when the gateway haven’t yet changed to its desired state(i.e. if code return errors.New(LATTICE_RETRY) in the middle of reconciliation process )

My observation is this could be a regression issue, We didn't have this problem before until release v0.0.11?

Not experiencing this after #287, should not fall into loop after the timestamp change.
