Issue Plesk Let's Encrypt extension still leaves garbage behind in .well-known/acme-challenge/ directories

Posted my question here as well, since it's become a major nuisance for us and we want it fixed:
[FIXED BUG] Let's Encrypt challenge files are not removed from .well-known/acme-challenge/ directories

Just stumbled on this article after a major clean up on our Linux plesk servers, littered with millions of such stale files. Now running Plesk Obsidian
Version 18.0.23 Update #3 with Let's Encrypt extension Version 2.8.6-571 on all of them since 5th of February and we're still seeing thousands of challenge files created and left scattered around. Both in /var/www/vhosts/<vhost>/httpdocs/.well-known/acme-challenge/ as well as /var/www/vhosts/default/htdocs/.well-known/acme-challenge/


How should we configure Plesk to have this issue fixed once and for all? Reading Managing Let’s Encrypt Settings I haven't found anything that tackles the removal of old files. Are we supposed to set up our own cron jobs for this?

There should be a cronjob configured to remove these files if they are older than 1 month:

$ sudo crontab -l -u psaadm | grep "remove-expired-tokens"

Output should be:

0       0       *       *       0       /opt/psa/admin/bin/php -dauto_prepend_file=sdk.php '/opt/psa/admin/plib/modules/letsencrypt/scripts/remove-expired-tokens.php'
