This would be something like the below (modulo terrible indentation) using currently speced primitives?

function getScreenBBox(element) {
  let ctm = element.getScreenCTM();
  let localBBox = DOMQuad.fromRect(element.getBBox({fill: true, stroke: true, markers: true}));
  let clientBBox = new DOMQuad(localBBox.p1.matrixTransform(ctm),
      localBBox.p2.matrixTransform(ctm),
      localBBox.p3.matrixTransform(ctm),
      localBBox.p4.matrixTransform(ctm));
  return clientBBox.getBounds();
}
