Fired triggers could be linked to random hosts on maps

foreach ($triggersFromMonitoredHosts as $triggerId => $trigger) {
    foreach ($trigger['hosts'] as $host) {
        $hostd = $host['hostid'];

        if (isset($hostIdToSelementIds[$hostId])) {
            foreach ($hostIdToSelementIds[$hostId] as $selementId) {
                $selements[$selementId]['triggers'][$triggerId] = $triggerId;
            }
        }
    }
}
