Recently, for slow test environments, journalctl --sync was added to the loop in the timeout. However, journalctl --sync may be slow in such systems, and timeout easily triggered during syncing. Hopefully, reading journal with --follow and grep the output with an expected line should be efficient. Hopefully fixes #32712.
