Currently crash safe slave doesn't work on RocksDB storage engine. This is because Xid binlog event is not written at transaction commit in RocksDB, but Query event is written instead. This needs to be changed. To make Xid event is written at RocksDB commit, it is needed to add handler::prepare() method. Empty definition is fine.
In addition to that, slave_relay_log_info and slave_gtid_info, slave_worker_info tables need to be changed to RocksDB.
