Innodb history length keeps growing

I have a server where the history length keeps growing. At first we had them in shared system space but we moved them with using innodb_undo_tablespaces. This did not helped us either.

Right now the length is 124355327 and the server is not making transactions right now (for 1 hour) just to see if the purge starts. It's pretty idle.

Ihave the following parameters, most of them are extreme just to trigger some purge actions.

{{MariaDB [(none)]> show global variables like "innodb%purge%";

innodb status:

Purge done for trx's n:o < 258032014 undo n:o < 5633661 state: running

History list length 124560317

Looks a little bit like #MDEV-29401 but that one should be fixed by the version we are already using.
