if a ListView has 

highlightRangeMode: ListView.ApplyRange
highlightFollowsCurrentItem: true

and preferredHighlightBegin/preferredHighlightEnd  set,  if clicking on a list item sets it as current item, when the "old" current item is scrolled out of view, after clicking on a new one it will always be performed an animation from the position of the old current item visible to the new current item visible, making the animation look quite glitchy.

To trigger it in the attached example, scroll down the list which has already the index 0 as current. and click on a bigger index, like 50 or so.  The listview position will be moved again to have the index 0 visible, and then an animation to show the new one at 50 will be performed.
