::backdrop only applies to "top layer" elements so there's some
special-casing we can do to simplify the layout and rendering of
::backdrop. If you allow ::backdrop on non-top-layer elements then it can
appear anywhere.

I don't know.

I guess I don't understand why we need backdrop-filter at all. Why can't
authors use BackgroundImage with the 'filter' property to get the same
effects? Is it because they'd have to use SVG filters and a standalone CSS
property is easier to use?
