Doing multiple `for_each_in_subtree()` passes was kind of a hack. We can resolve everything in a single pass with a little more control over the layout process. This also fixes a few minor issues like the sizing of nested `<g>` elements. More work is needed here though as this is still fairly ad-hoc. Note: This does regress `css-namespace-tag-name-selector.html`, previously SVG text within `<a>` elements would appear. However, this was only because `for_each_in_subtree()` would blindly look through the InlineNodes from the unimplemented `SVGAElement`s.
