oc_text_steps seems to not be cleanupped

[sistason]

Describe the bug
In the database, oc_text_steps grows to ~3GB because it seems the cleanup does not run.
3GB is more than half my entire database size, so I expect it to become a bigger problem in the future.

I'd like to ask for hints to debug this.

Screenshots

It looks like the cleanup job runs and does "something". is there a way to get the logs of the job?

oc_text_steps does not seem to be cleanupped, even though the session_id/timestamps seem really old

select session_id,timestamp,length(data) from oc_text_steps where document_id=3212894;

the oc_text_sessions seem to be in order, though

The table is very big in general, the oc_text_steps.ibd is 2.7GB in size
