It may actually work, since clippedOverflowRectForRepaint does include the outline box (see SVGRenderSupport::computeFloatRectForRepaint).

Also, it couldn't be any worse than what we have today, since we're not doing anything special for PaintPhaseOutline :)

Quick patch for coming for a test drive.
