Open the attached test case.
Expected: Three rectangles filled with green.
Actual results: Two rectangles filled with black.
The first rectangle is filled using a gradient resource. The second rectangle is filled with a pattern resource. And the third rectangle is a <use> element referencing a filter resource.
Because the page has the tag <base href="/">, all the links to the resources are broken.
