Use Layout/Box tree order instead of DOM Tree order #209

Per @mfreed7- " What matters is that the anchor element gets laid out first, and the anchored/positioned element gets laid out after that."

DOM and Layout/Box tree order are quite similar, but aren't identical. For a counter example, see https://github.com/web-platform-tests/wpt/blob/master/css/css-anchor-position/anchor-position-top-layer-005.html.
