Description:

Sometimes the inline validation error for the host interface is not displayed in the item.edit form after scrolling up or down for the "Type" field.

Steps to reproduce:

1. Create host with no interface
2. Create item for host
3. Choose "Browser" for Item type
4. Hold up arrow and scroll till "Zabbix agent" and observe
5. Observe "Host interface" inline validation error

Result:

Error is blinking - assume this is expected. Sometimes error is not present, when Type = Zabbix agent

Please see screencast:

Expected:
Error should appear
