The attached SVG file contains a symbol which uses percentages of the instance size to draw circles. The image is drawn as expected (only green circles) with zoom=1, but after zoom the percentages are no longer calculated correctly (red circles show where the green ones should have been). Safari and Chrome both fail, Firefox and Opera render the image correctly at all zoom levels.
