Summary SVG element's transform and transform-origin computed values are incorrect

An SVG element styled with `transform` and `transform-origin` renders correctly, but returns wrong computed values. See http://jsbin.com/yuhoxum/edit?html,js,output It styles an SVG rect shape with `transform-origin: 50% 50%; transform: scale(0.5)`. The rendering appears to be fully correct. However, reading styles and computed values yields: computed transform: none computed origin: 0px 0px style transform: scale(0.5) style origin: 50% 50% Styles are correct, but computed value for origin = `0px 0px` and transform = `none` are both wrong.

It appears, per transform-box spec, the current rendering is also incorrect. The implied transform-origin should be referenced against SVG's viewbox and not the element's border-box. See https://developer.mozilla.org/en-US/docs/Web/CSS/transform-box

Safari, Chrome, and Firefox all agree on rendering for this test case. I don't believe there is any remaining compatibility issue.
