I'm unsure about lightning-color. This is a CSS property and should be be handled via SVGStyledElement, RenderStyle and the Renderer of primitives. Also you checked in a reference image with fail messages. Guess this is not expected.

Yes, you are right. My mistake. :$

I don't know, but FEDiffuseLighting handles the update of lighting-color the same way.

There is also a SVG _attribute_ "lighting-color", despite the CSS property, I think handling the attr update this way is just fine, no? Or is your concern that "lighting-color" attribute should be mapped to a CSS property, and thus updates should be handled differently?

Reni, can you check wheter the lighting-color attribute is properly mapped to it's corresponding CSS attribute? (Are changes to the attribute value, immediately visible in the computed style, even _without_ your patch?)

Dirk is right, SVGStyledElement properly maps diffuse_lightingAttr to it's corresponding CSS property (mapToEntry & friends).
That means that the RenderSVGResourceFilterPrimitive (the renderer created for SVGFEDiffuseLighting/SVGFESpecLighting) should receive styleDidChange/styleWillChange calls, where you can catch those style changes.

The dynamic update of CSS related SVG props are handled in #56906.
