when zbbix-proxy is down，the triggers “ Zabbix agent is not available” don‘t work

[lhb6540]

when zbbix-proxy is down，the triggers “ Zabbix agent is not available” of all hosts monitored by proxy don‘t work.
but if the zabbix-proxy is work normally，only the zabbix-agent of the hosts monitored by proxy down， the trigger “ Zabbix agent is not available” work normally.
Is the logic of the trigger designed like this? or is it a bug?
This phenomenon can be reproduced on zabbix 5.0 LTS and 6.0 LTS

nodata .... "Since Zabbix 5.0, the 'nodata' triggers monitored by proxy are, by default, sensitive to proxy availability - if proxy becomes unavailable, the 'nodata' triggers will not fire immediately after a restored connection, but will skip the data for the delayed period. Note that for passive proxies suppression is activated if connection is restored more than 15 seconds and no less than 2 & ProxyUpdateFrequency seconds later. For active proxies suppression is activated if connection is restored more than 15 seconds later.

To turn off sensitiveness to proxy availability, use the second parameter, e.g.: nodata(5m,strict); in this case the function will work the same as before 5.0.0 and fire as soon as the evaluation period (five minutes) without data has past."
