SVGEllipseElement::parseAttribute() and SVGCircleElement::parseAttribute() both forbid negative values for these properties. The CSSParser should be consistent with setting these properties through setAttribute().
The type of these properties is <length-percentage>, https://www.w3.org/TR/css-values/#typedef-length-percentage, which requires specifying the unit if it's a length.
