Created attachment 467734 [details] red-100x100.png Open the attached test case. Expected: Only half of the rectangles should be displayed. Result: The whole rectangles are displayed. https://developer.mozilla.org/en-US/docs/Web/CSS/image/image#image_fragments suggests a bitmap image fragment implementation. When specified as mask-image, an image fragment should only be used to mask the target element.
