Re: [fxtf-drafts] [filter-effects-2] Backdrop filters should not use BackgroundImage (#53)

I want to join the calls for making `backdrop-filter: blur(10px)` do the reasonable thing which I, as a developer, expect it to do:
Blur everything behind the element with the property set.

The concept of "Backdrop root" is alien and overly complex to me at best.

The current state is incredibly frustrating, and getting above reasonable behavior working in Chrome has added an INSANE amount of complexity to my app, with all my animations written in a way to conditionally not animate opacity in the mobile layout that uses backdrop-filter, all backdrop-filter being set on pseudo-elements, to avoid making the connected element a backdrop root. Now I have to also make that blur progressive for a new redesign and it's probably going to make the app 90% workarounds for this issue and 10% actual code.

Native macOS apps can do it just fine, so it's not a performance problem.
