It still has some quirks:

  • behavior is strange when the pop-up is above the combo box (whereas it is usually below) [fixed; when the pop-up is above the combo box, the drag-handle is at the top and the top edge moves while the bottom edge stays fixed at the combo box]
  • the formula for resetting the number of visible items after dragging occurs is not quite right [fixed; dragging now snaps to whole-item positions]
