It's because "modern" web developers are not writing web pages in standard html, css or js. Instead, they use javascript to render the entire thing inside a root element. This is now "standard" but breaks any browser that doesn't (or can't) support javascript. It's also a nightmare for SEO, accessibility and many other things (like your memory, cpu and battery usage). But hey, it's "modern"!
