QML ListView - List Header does not appear when the user scroll to the first item on the list

Pre-condition:

• Listview contains a header and several items
• The user has scrolled to the end of the list so that header is not visible (outside of the screen)

Issue:

• The user start to scroll up using HW keys
  => The header doesn't appear to the screen when the focus is on the first item.

The user must use mouse to get Header visible.
