Creating the GraphicsDropShadow with color equal to auto color = m_shadowColor.colorWithAlpha(m_shadowOpacity); is wrong since it will override the alpha channel of the drop-shadow filter with the shadow opacity. For example an element with the following css filter: drop-shadow(15px 15px 0px rgba(0, 0, 0, 0.5)); will display a black drop shadow effect for this element. This css filter appears in the expected test page: imported/w3c/web-platform-tests/css/filter-effects/css-filters-animation-drop-shadow-expected.html.
