Description
Note: I've set it to 10.3 because that's where most tests run, and where I am thus getting it regularly; but it might well be that 10.2 is also affected. Since I don't have anything marginally reproducible so far, I cannot make sure.

I think that this can affect 10.2 just as well. There, the function is named trx_purge_add_update_undo_to_history() and only invoked at the commit of transactions that generated certain types of persistent undo log records. In 10.3, the function trx_purge_add_undo_to_history() is invoked for any persistent undo log.
The solution is to register as internal the numerous background transactions that are created for FULLTEXT INDEX maintenance.
