transaction::bf_abort() check is transaction is active, i.e. it has been started by transaction::start_transaction(), and only aborts victims with active transaction.
However, some client sessions in MySQL/MariaDB side can hold locks, and end up as brute force abort victims, even though they have not started transaction yet. One such example is Create Table As Select execution (CTAS), which causes eternal hang with galera.galera_concurrent_ctas test
