A property of CSS zoom is that computed styles should not reflect the zoomed value. One reason for this is to support round-tripping. This is generally supported across Chromium, Gecko, and Webkit. In SVG though, Webkit incorrectly unzooms computed styles (see attached testcase). Expected (Chromium, Gecko): svg width computed style: 100px rect width computed style: 50px div width computed style: 100px Actual (Safari 17.4 WebKit 19619.1.16.3): svg width computed style: 100px rect width computed style: 25px div width computed style: 100px 2042987 1 webkit-bug-importer 2024-06-25 10:12:13 -0700 <rdar://problem/130513052> 2161399 2 ahmad.saleem792 2025-11-26 00:32:10 -0800 WebKit ToT (303562@main): svg width computed style: 100px rect width computed style: 50px div width computed style: 100px Safari Technology Preview 232: svg width computed style: 100px rect width computed style: 50px div width computed style: 100px 471700 2024-06-18 10:11:19 -0700 2024-06-18 10:11:19 -0700 Testcase showing computed style of zoomed values in html and svg svg_zoom_computed_style.html text/html 625 pdr PCFET0NUWVBFIGh0bWw+CjxkaXYgc3R5bGU9Inpvb206IDI7Ij4KICA8c3ZnIGlkPXN2ZyB3aWR0 aD0iMTAwIiBoZWlnaHQ9IjUwIiBzdHlsZT0iYmFja2dyb3VuZDogbGlnaHRibHVlOyI+CiAgICA8 cmVjdCBpZD1yZWN0IHg9IjAiIHk9IjAiIHdpZHRoPSI1MCIgaGVpZ2h0PSIyNSIgZmlsbD0icmVi ZWNjYXB1cnBsZSIvPgogIDwvc3ZnPgogIDxkaXYgaWQ9ZGl2IHN0eWxlPSJ3aWR0aDogMTAwcHg7 IGhlaWdodDogNTBweDsgYmFja2dyb3VuZDogbGlnaHRncmVlbjsiPjwvZGl2Pgo8L2Rpdj4KCjxk aXYgaWQ9ImxvZyI+PC9kaXY+CjxzY3JpcHQ+CiAgbG9nLmlubmVySFRNTCArPSBgc3ZnIHdpZHRo IGNvbXB1dGVkIHN0eWxlOiAke2dldENvbXB1dGVkU3R5bGUoc3ZnKVsnd2lkdGgnXX1gOwogIGxv Zy5pbm5lckhUTUwgKz0gYDxicj5gOwogIGxvZy5pbm5lckhUTUwgKz0gYHJlY3Qgd2lkdGggY29t cHV0ZWQgc3R5bGU6ICR7Z2V0Q29tcHV0ZWRTdHlsZShyZWN0KVsnd2lkdGgnXX1gOwogIGxvZy5p bm5lckhUTUwgKz0gYDxicj5gOwogIGxvZy5pbm5lckhUTUwgKz0gYGRpdiB3aWR0aCBjb21wdXRl ZCBzdHlsZTogJHtnZXRDb21wdXRlZFN0eWxlKGRpdilbJ3dpZHRoJ119YDsKPC9zY3JpcHQ+Cg==
