Re: Interface SVGElement
https://svgwg.org/svg2-draft/single-page.html#types-InterfaceSVGElement

As far as I can tell, this is the first version of the spec since className was added to the Element interface in DOM level 2 (2002). SVGElement in SVG 1.2 Tiny didn't include className in its uDOM definition.

Should the spec provide guidance on how implementations should handle the conflict between SVGElement.className and Element.className?
