The attached test-case shows white, but it should show some green per https://drafts.fxtf.org/css-masking/#placement:

The compositing model follows the SVG compositing model [SVG11]: First the element is styled under absence of filter effects, masking, clipping and opacity. Then the element and its descendants are drawn on a temporary canvas. In a last step the following effects are applied to the element in order: filter effects [FILTER-EFFECTS], clipping, masking and opacity.

Looks like Chromium also gets it wrong, only WebKit does it right it seems. This (somehow) fails also before my patch from bug 1524966, and before my fix from there.
