Hmm, that's not a small one... You found this by chance Antti? Or did the patch make you suspicious? :-)

The Suits subtest is about calling svgElement.setAttribute('transform','translate...". in a repeated manner. r291788 went from "attribute changed + set needsLayout" to "attribute changed + invalidate style" which is fine as long as the attribute is translated to a RenderStyle property, however SVG transform is special and internal to SVGGraphicsElement and it does not require style invalidation. Will post a patch soon.
