Row-based triggers: Assertion `i == tables_to_lock_count' fails with a trigger on row-based event while slave operates in SBR

          Description

          In the test case below, the slave has binlog_format STATEMENT, while master writes events in row format. Normally, the replication should abort on executing a row event, complaining that it cannot be written to the slave's binlog. With RBR triggers, we are getting an assertion failure instead.
