According to css-masking spec: Make clear that the used value of the properties mask-image, mask-repeat, mask-position, mask-clip, mask-origin and mask-size must be ignored for <mask-source> So we still have take mask-composite into account. [1] https://drafts.fxtf.org/css-masking-1/#the-mask-origin
The relevant paragraph from the spec is: "The used value of the properties mask-repeat, mask-position, mask-clip, mask-origin and mask-size must have no effect if <mask-reference> references a mask element. In this case the element defines position, sizing and clipping of the mask layer image." Note that mask-image isn't in there. Though it's incorrectly listed in the changes section as: "Make clear that the used value of the properties mask-image, mask-repeat, mask-position, mask-clip, mask-origin and mask-size must be ignored for <mask-source>, not the properties."

Comment on attachment 8756188 [details] MozReview Request: Bug 1275451: Part 1. Respect mask-composite while composing a SVG mask layer https://reviewboard.mozilla.org/r/54998/#review51890 ::: layout/svg/nsSVGIntegrationUtils.cpp:485 (Diff revision 2) > // Multiple SVG masks interleave with image mask. Paint each layer onto maskDT > // one at a time. > for (int i = svgMaskFrames.Length() - 1; i >= 0 ; i--) { > nsSVGMaskFrame *maskFrame = svgMaskFrames[i]; > > + CompositionOp compositionOp = (i == svgMaskFrames.Length() - 1) So this also changes behavior for the bottom layer if the bottom layer is an image mask, right? Can we add a reftest for that? Or is there already a reftest for it that was failing before this patch?

Or is there already a > reftest for it that was failing before this patch? Inside nsCSSRendering::PaintBackgroundWithSC[1] we use this logic already. Maybe I should remove that check in PaintBackgroundWithSC. [1] https://dxr.mozilla.org/mozilla-central/source/layout/base/nsCSSRendering.cpp#3091

Ah, I see. Yeah, I think it would be a good idea to remove that check. Can be done in a separate patch or bug.
