This allows creating reusable "components" in the form of clip paths, gradients, patterns and markers.

I guess we'll need to add some fuzziness parameters. https://wpt.fyi/results/svg/linking/reftests/url-processing-fetch-properties-001.sub.svg This is testing "anonymous" state for CORS. Looks like there could be disagreement there. I filed https://bugzilla.mozilla.org/show_bug.cgi?id=1923109 for discussion. https://wpt.fyi/results/svg/linking/reftests/url-processing-fetch-properties-002.sub.svg This passes everywhere because it tests that a resource is not allowed to load (and thus the fallback color is used instead). /fs > > >> >> >> Flag name on chrome://flags >> >> Finch feature name SvgExternalResources >> >> Requires code in //chrome?
