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. 2169139 1 simon.fraser 2026-01-04 12:02:19 -0800 This happens because the input image to the `<feImage>` becomes huge, and we start scaling down incorrectly. 2169140 2 webkit-bug-importer 2026-01-04 12:02:36 -0800 <rdar://problem/167516452> 2169423 3 simon.fraser 2026-01-05 11:34:01 -0800 Pull request: https://github.com/WebKit/WebKit/pull/56096 2169526 4 ews-feeder 2026-01-05 17:48:04 -0800 Committed 305136@main (c08dafc2c51a): <https://commits.webkit.org/305136@main> Reviewed commits have been landed.
