RESOLVED DUPLICATE of bug 256617203711
SVGAnimatedNumber should throw a TypeError exception when setting its baseVal to NaN or Infinity

Summary SVGAnimatedNumber should throw a TypeError exception when setting its baseVal...

The specs: https://www.w3.org/TR/SVG/types.html#InterfaceSVGAnimatedNumber do not say that this should happen. But the WPT test https://wpt.fyi/results/svg/types/scripted/SVGAnimatedNumber.html?label=master&label=experimental&aligned expects this to happen. I think throwing an exception and keeping the value unchanged is much better than setting it to NaN.
