Sites you click start responding, and the web lays out like the reference browser

This is the largest release so far, and it does two big things. First, the interactive web starts working. Nearly every site on the web wires up its buttons, menus and tabs by putting a single listener on a shared container and letting clicks travel up to it - and that travel was never happening, so clicking things did nothing. Clicks, and every other kind of page event, now move up through the page the way they should, which is the difference between a page you can read and a page you can use. Sites built with Vue now start up and run their templates instead of failing at load; the standard way scripts set a site's own style values works, which nearly every modern design system needs; and a whole batch of everyday building-block commands that pages call constantly - checking whether one element holds another, inserting content next to an element, swapping a class, stepping through a set of values - were simply missing and are now present. Second, the old and real web lays out and paints like the reference browser. The single biggest visual difference left on a large encyclopedia is gone: the opening paragraphs had been sitting in a blank column beside the fact-box on the right, and they now wrap around it. The most common float-clearing layout trick on the web works, so menu bars stop landing on their logos. And more than twenty rendering faults were fixed by putting Floati next to the reference browser and comparing to the pixel: gradients that fade to transparent, dashed and dotted and double borders, round photo crops, text that trails off with an ellipsis, and the front-to-back order that overlays and dropdowns stack in. Under the hood the JavaScript engine also got more honest: deleting a property really removes it, frozen and read-only objects reject changes, hidden properties stay hidden, and backslashes in template text survive.
