This is one of the last sites that I would criticise for use of client-side JavaScript. It uses one small script to implement a few simple web components. The power required to run that script is negligible compared to what the browser itself requires merely to render static HTML. You probably produced more CO2 just breathing while writing that comment than can be cumulatively attributed to this script across all visitors to this site to date.
The shadow-DOM thing svnpenn commented on is a red herring. It doesn't interfere with keyboard scrolling, which works perfectly well. The shadow DOM is merely used to isolate CSS styling rules so that they apply to an instance of a component rather than sharing a single global namespace. The elements are still rendered as part of the parent document.
