Issue Log Browser: PHP Warning „Undefined array key ‘user’“ in ImapLoginProcessor.php

Ubuntu 20.04.6 LTS
Plesk version and microupdate number
Plesk Obsidian 18.0.74 Update 3
Hello,
after re-enabling the Log Browser extension, my Plesk server is constantly logging the following warning in /var/log/plesk/panel.log:
PHP Warning: Undefined array key "user"; File: /opt/psa/admin/plib/modules/log-browser/library/Injest/ImapLoginProcessor.php, Line: 26
The warning is generated continuously by a sw-engine async task and causes heavy log spam.

I already applied the known workaround in panel.ini:
[ext-log-browser]
mailQueue.customerAccess = false

and restarted sw-engine and sw-cp-server, but the warning still appears.
This seems to be related to IMAP login parsing, not the mail queue itself.
Has this issue already been identified as a bug in the Log Browser extension, or is there an additional setting to disable IMAP login processing?
Log Browser extension: latest available via CLI reinstall

Thanks in advance.
