    <!-- Note: The following elements will be superimposed.  If they weren't
         positioned, then they'd be flex items, and their relative "order"
         values would force the first one (with the red child) to paint on top.
         But since they're absolutely positioned, they're not flex items &
         "order" has no effect, and so the lime one should end up on top. -->
