Steps to recreate: 1. Display the following SVG in WebKit so that it fills its container: <svg viewBox='0 0 100 100' xmlns="http://www.w3.org/2000/svg"> <defs> <marker id='circle' viewBox='0 0 2 2' refX="1" refY="1" markerWidth="2" markerHeight="2" markerUnits="userSpaceOnUse"> <circle cx='1' cy='1' r='1' fill="red" /> </marker> </defs> <line x1='2' y1='2' x2='98' y2='2' stroke='black' stroke-width='2' vector-effect="non-scaling-stroke" marker-start='url(#circle)' marker-end='url(#circle)'/> </svg> 2. Resize the window/container. Marker elements change size while the stroke of the line does not. Replacing userSpaceOnUse with strokeWidth does not resolve the issue. 1953045 1 webkit-bug-importer 2023-05-04 16:54:19 -0700 <rdar://problem/108921711>
