Here is the info when dump the display list, it is easier for us to map the display items to app.

nsDisplayTransform p=0xaf7312f0 f=0xb278d150(Block(div)(23) class:icon) z=3 bounds(13360,52560,5460,6980) layerBounds(13360,52560,5460,6980) visible(13360,52560,5460,6980)
  Background p=0xaf7311a0 f=0xb278d150(Block(div)(23) class:icon) z=3 bounds(560,0,5280,5280) layerBounds(560,0,5280,5280
  LayerEventRegions p=0xaf731228 f=0xb278d370(HTMLScroll(span)(0) class:title) bounds(0,0,0,0) layerBounds(0,0,0,0)
