  <!-- Test that position:fixed elements scroll with the layout viewport.

       Scroll the window (i.e., the layout viewport) to (0, 1000). An async
       scroll of -50 CSS pixels will move both the layout and visual viewport
       up by 100 screen pixels (since async zoom is set to 2.0). The div should
       remain at top-left corner of the layout viewport. -->
