[Webkit-unassigned] [Bug 162760] [css-filters-2] Parent stacking context of backdrop-filter needs to isolate itself

--- Comment #3 from Tien-Ren Chen <trchen at chromium.org> ---
But that would be undefined if the backdrop-filter element is inside of an open group effect. I saw a proposal somewhere that in such case we treat parent effects to be no-op and replace special blending with src-over when we draw the backdrop.

So for example:

A + opacity(B + C) * opacity(D + E + Backdrop + F + G)

Where '+' denotes src-over and '*' denotes some special blending. The backdrop will be resolved as:

A + opacity(B + C) + D + E

Is that what we intended to implement and make into the spec?
