REVISION SUMMARY
  As of Qt 5.9, QQuickWindow synthesizes a hover event once per frame.
  This interferes with keyboard navigation when having the mouse
  pointer above any item, because after navigating away with the arrow
  keys, the next synthesized hover event will cause the item below the
  pointer to become the current item again. This patch addresses this
  by rejecting onPositionChanged with identical coordinates from the
  last event.
  
  It also optimizes the delegate by turning its root item from
  MouseArea to Item and turning the per-delegate context menu instance
  into a per-view one.

  R119 Plasma Desktop
