A Zabbix-Admin may not edit a host anymore when host is member of a host group the Zabbix-Admin has no permission to.

While Zabbix-Admin still has write permission to the host he or she is for example not allowed to enable or disable monitoring when editing the host.
This is likely caused by implicitly updating the host group memberships to the best of knowledge (not including host groups the user has no permission to) - what is correctly not allowed.

Even when there are ways to work-around this issue by mass-update, toggle-hyperlinks, ... it would be nice to improve editing of hosts and possibly other related elements to only update properties that have changed.
