In the data collection process, the collected data is within the scope of the triggers's flip-flop, but even then, the recovery will still be restored and the recovery notification is sent
For example: I was

{zabbix server:user-login.last trigger expression (}>5)

, now item value value is 7, the current state is fault, the next second, will enter into the recovery state, but item value is still 7, after it has been in circulation, fault, fault recovery, and then trigger fault recovery fault.
