Description Frédéric Wang (:fredw) 2019-06-07 01:52:24 PDT

Just opening this for the record...

4 years ago, the SVG WG resolved to remove SVGTests.hasExtension due to lack of use and being a poor API.
It was removed from Chromium at that time and has been removed from Firefox recently

Sent to webkit-dev too: https://lists.webkit.org/pipermail/webkit-dev/2019-June/030659.html

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.

@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?
