 Description   

There was some clean-up to the file srv0mon.cc in the latest MariaDB Server releases, to make more use of MONITOR_EXISTING (instead of duplicating some bookkeeping, mirroring existing status variables that were extended in MDEV-18582).

Unfortunately, it looks like the counter trx_rseg_history_len accidentally lost the flag MONITOR_DEFAULT_ON as part of this clean-up.

Thanks, this looks good in the 10.6.14 build you pointed me to.
