Description Antti Koivisto 2019-05-29 07:05:53 PDT 
With sticky positioning in non-stacking context overflow you currently get structure like

FrameScrollingNode
  OverflowScrollingNode
  StickyNode
    PositionedNode

where StickyNode and PositionedNode reference the same layer. Sticky doesn't get applied at all when the overflow moves.
