As per bug 3537, rendering silently fails for SVG files that refer to external resources, even those on our own server. I propose that linking to external resources on the upload.wikimedia.org domain (using the xlink:href attribute of the image tag) be allowed.
Steps to Reproduce:
- Go to http://commons.wikimedia.org/wiki/File:Svg_to_wikipedia_jpeg_ref_test_2.svg.
- The full-size version works in browsers that support SVG. They successfully load http://upload.wikimedia.org/wikipedia/commons/0/0d/SuperDisk_top_rear_components.JPG. Check to see if a server-generated preview is properly displayed.
Actual Results: Rendering of the preview silently fails.
Expected Results: Rendering of the preview should succeed because the image is not stored on a different server (at least from the user's point of view) from the SVG.
