Does some CSS spec describe the order?

> In a last step the following effects are applied to the element in order: filter effects [FILTER-EFFECTS], clipping, masking and opacity.

> The compositing model follows the SVG compositing model [SVG11]: first any filter effect is applied, then any clipping, masking and opacity [CSS3COLOR].
