Loading a .png or .jpg as an <image> element within an SVG does not work. See example failing here: https://developer.mozilla.org/en-US/docs/Web/SVG/Element/image
This happens because SVG 2 does not require the xlink namespace before the href attribute. For example, this tag will not show the image in WebKit <image href="https://mdn.mozillademos.org/files/6457/mdn_logo_only_color.png" height="200" width="200"/> But this tag will show it because WebKit still supports SVG 1 only: <image xlink:href="https://mdn.mozillademos.org/files/6457/mdn_logo_only_color.png" height="200" width="200"/> *** This bug has been marked as a duplicate of bug 153854 ***
