ListView section, problem when changes currentIndex

I have a QML ListView with sections, preferredHighlightBegin/End and highlightRangeMode=ListView.StrictlyEnforceRange. When I change the currentIndex with key up or down (which call decrementCurrentIndex() or incrementCurrentIndex()), the view moves on the section header and not on the first item of the section (see the example in attachment). When I change the currentIndex by flicking the view there is no problem.
