Steps to reproduce:
1. Create New host with triggers
2. Create map with trigger element
3. Add multiple triggers from New and "Zabbix server" hosts
4. Type host macro, for example {HOST.HOST}, in icon label
5. Save map and open map view page
Result: {HOST.HOST} expanded as "Zabbix server", but there are also triggers from another host
Expected result: host macros {HOST.*} shouldn't be expanded, if added multiple triggers. If added one trigger host macros can be expanded
