When animating a <polygon> point list with a "spring" animation, at various points in the animation, the computed pointlist contains NaNs and throws console errors.
Animate the points of the element, and use a spring animation.
Observe that you get a bunch of complaints about NaNs in your error console.
When the animation type is not "spring", the NaN errors are not thrown (though one "expected number, 'undefined'" message is thrown per polygon element).
Expected behavior
When an SVGPointList would produce NaNs, it should not incorrectly attempt to set the pointlist with NaNs on the element.
