karlcow has just created a new issue for https://github.com/w3c/csswg-drafts: == [css filters] supported values for the "in" attribute == the `in` attribute identifies input for the given filter primitive. It is defined in https://drafts.csswg.org/filter-effects/#element-attrdef-filter-primitive-in as: ``` in = "SourceGraphic | SourceAlpha | BackgroundImage | BackgroundAlpha | FillPaint | StrokePaint | <filter-primitive-reference>" ``` only * `SourceGraphic`, * `SourceAlpha` are supported by browsers to the best of my knowledge Even WPT is minimal on the topic. https://wpt.fyi/results/css/filter-effects Should it be removed from the spec?
