Problems panel does not support event severity change

[memfiz]

From Zabbix 4.0 there is a possibility to change the severity of the event. This overrides trigger priority. There is a new property "severity" for the event object in Zabbix:

Severity change of the event does not appier in the problems panel, the alarm is still shown with the default trigger severity. That also impacts trigger filtering by severity: problems with changed severity are still shown in problem panel even if current severity is switched off in options.

If there is a severity in last event of a trigger (new zabbix version) it should be taken for displaying in the problems panel.
