Created attachment 149539 [details] Same resource downloaded twice If I have a SVG stack (reference different parts of the same file), the SVG gets downloaded on every usage: <object data="http://dahlström.net/tmp/sharp-icons/svg-icon-target.svg#plus"></object> <object data="http://dahlström.net/tmp/sharp-icons/svg-icon-target.svg#chart"></object> The both links above reference the same SVG file. Web inspector says that the file is downloaded twice. The idea of SVG stacks is to avoid that.
