So as you may know we have, knowledge.. or in the old black books of web witchcraft; the checkbox hack. I wonder though; did anyone ever go the final mile and create a kinda generalized “progressive polyfill” to fix the semantics of this so called hack? Tangentially, a query for a details/summary polyfill brings up either rstacruz/details-polyfill or chemerisuk/better-details-polyfill with demo. Interesting.
