What’s more interesting is how bad Safari fails these tests (and how Firefox is on a negative trend the last few years) … which saddens me given Safari is my primary browser.
I have a gripe with those tests because they include a bunch of non-standard APIs whose status is literally "not on any standard track" (e.g. Background Fetch) and many of whom are opposed by both Safari and Firefox (e.g. WebHID, WebUSB)
