It was removed from Chromium at that time and has been removed from Firefox recently 1542780 1 fred.wang 2019-06-07 01:58:12 -0700 Sent to webkit-dev too: https://lists.webkit.org/pipermail/webkit-dev/2019-June/030659.html 1545815 2 rniwa 2019-06-18 14:38:00 -0700 As I mentioned in webkit-dev, the key question here is whether there is any web content that relies on this feature either intentionally or accidentally; e.g. iOS specific web content. 1549234 3 sabouhallawa 2019-07-01 09:20:21 -0700 SVG 2 (W3C Recommendation): https://www.w3.org/TR/SVG2/types.html#InterfaceSVGTests SVG 1.1 (W3C Recommendation): https://www.w3.org/TR/SVG11/types.html#InterfaceSVGTests 1580050 4 fred.wang 2019-10-15 03:19:20 -0700 @Ryosuke: It looks like LayoutTests/web-platform-tests/mathml/relations/html5-tree/mathml/relations/html5-tree/required-extensions-1.html (test for SVGTests.hasExtension and MathML namespace) was removed in bug 200470. Should we import it back into LayoutTests/mathml? 1782837 5 fred.wang 2021-08-09 00:31:04 -0700 *** This bug has been marked as a duplicate of bug 204125 ***
