Created attachment 472873 [details] [Screenshot] Firefox: Good To reproduce navigate to https://www.github.com and hover mouse over the "cards". Card should skew following mouse hover but child layer is not getting affected by perspective transform. Expected Behavior (as per CSS spec): "Yhe perspective and perspective-origin properties can be applied to an element to influence the rendering of its 3d-transformed children, giving them a shared perspective that provides the impression of them living in the same three-dimensional scene"
