Created attachment 477899 [details] Test The attachment shows a bug where a filter referencing an SVG element with a huge stroke fails to display. The same SVG stand-alone displays fine. Works: ``` <line x1="-50%" x2="150%" transform="rotate(45)" stroke="blue" stroke-width="300%" stroke-dasharray="15%"></line> ``` Fails: ``` <line x1="-50%" x2="150%" transform="rotate(45)" stroke="blue" stroke-width="100%" stroke-dasharray="15%"></line> ``` Even when the blue dashes show, the red rectangle has the wrong size.

This happens because the input image to the `<feImage>` becomes huge, and we start scaling down incorrectly.
