The root element is included in the old state, but not the new, and is the first name in the namedElements map. Each frame during updatePseudoElementTree, `buildPseudoElementGroup` is called for the root, and nothing is created (as expected).. currentGroup then gets moved to the previous sibling, which is nullptr, and then is in a broken state for further iterations. All other iterated names then create new renderers, without removing the existing ones.
