Moving the thing that wants a whole-page filtered backdrop to be higher in the DOM structure.

This is indeed already a requirement for a number of things in CSS; stacking contexts are very definitely **not** no-ops for a number of things. Why is backdrop-filtering, in particular, special in this regard, such that it should ignore the "layering" rules that several other related CSS features adhere to?
