There is a gap between the window header and the row of tabs in the popup window.
Steps to reproduce:
- Find a Host with a lot of items (like default Zabbix server)
- Go to Items of the Host
- Select all the Items
- Press Mass update button (scrollbar should appear in the popup)
- Scroll down the list
The gap is present between the window header and the row of tabs: The_gap_mass.gif.
No gap between.
