This bug is related to bug 32378 and needs the same fix for Cairo and Qt.
Created attachment 44679 [details] correct color spacetransformation SVG Filter for Qt, Cairo ImageBuffer::platformTransformColorSpace shouldn't transform the alpha channel on sRGB <-> linearRGB on Qt, Cairo.
style-queue ran check-webkit-style on attachment 44679 [details] without any errors.
Comment on attachment 44679 [details] correct color spacetransformation SVG Filter for Qt, Cairo Looks sane. Obviously needs updates to those tests too.
