Use of bleeding edge Javascript features makes taking the survey infeasible in most non-corporate browsers

I've been taking these yearly surveys for a couple years now. In the past they worked in all browsers. But the 2025 survey uses bleeding edge javascript to look pretty. And so it doesn't work in most (non-corporate) browsers.

The survey should be accessible, not bleeding edge. And if those bleeding edge components should fail it should have a proper html fallback. Instead I just get a header and a spinning dots ring forever.
