  pfUI's scroll bar for ClassicAPI's ScrollBox: a thin track with a flat
  thumb. ScrollBarMixin needs Back and Forward steppers, so they exist but
  stay hidden. Hook it up with ScrollUtil.InitScrollBoxListWithScrollBar.

  A ScrollFrame for free-form content, with pfUIScrollBarTemplate inside its

  engine measures the scroll range from the shown frames inside it, so the
  content needs no height. Changes inside it are not measured until
  frame:UpdateScrollChildRect().
