<title>SVGSVGElement.viewBox.baseVal for an invalid (negative-dimension) viewBox attribute</title>
<meta name="assert" content="Tentative: SVG 2 does not define viewBox.baseVal when the viewBox attribute is invalid (negative width/height). This documents the current WebKit behavior (reset to {0,0,0,0}); Gecko and Blink retain the raw parsed values, so cross-engine results differ.">
