Hovercards for links to certain pages do not have the image at all visible, even though there is an appropriate image, and the image does load successfully. It appears that the problem is caused by the attribute "y" of the <image>s being set to the full height of the image, causing it to be pushed below the area of the SVG.
Example case: All links to the Wikipedia article [[Ouya]]. Browser tested: Google Chrome on Windows 7.
