For some reason, even though we provide an offset, Telegram sometimes sends us more events than we request, including newer events than the offset ID. Messages beyond the offset are then chopped off by the bridgev2 code, but we continue trying to backfill the portal thinking that there is more to backfill. This causes infinite backfill loops.
