ListView first element does not "reset" when exiting list visible area

When scrolling ListView, all the elements exiting the visible content area stop existing, except the list first element.

This can be verified by having two states on a delegate - default and "expanded", where in the expanded state the list element is larger than in the default state.
If the elements are expanded, and scrolled out from the visible area, all other elements are back in the initial default state when returning to the visible area, except the first element, which keeps the expanded state.
