Instead, lazily schedule evaluation of them before styling, much like we were doing for SVG. A subtle tweak is that we only remain scheduled while in the document. This allows us to use the "in document" bit plus the "mapped attributes dirty" bit to know our scheduled status. It also prevents doing silly work for disconnected elements, and having to do hashmap lookups on adoption and node destruction. Differential Revision: https://phabricator.services.mozilla.com/D181549
