Steps to reproduce:
- add dependent item to LLD (see "dependent item.png"). Use a separate application for them (like "TEST")
- wait until Zabbix will add them
- open list of items and filer by the application
- select some them to highlight and note current position/order (see order1.png)
- refresh the page (see order2.png)
Frontend will display them in a different place. They are not sorted by name
The items should be sorted by name.
