This one appears to be caused by accumulateOffsetTowardsAncestor adding the offset in:

                RenderRegion* region = toRenderMultiColumnFlowThread(parentLayer->renderer()).physicalTranslationFromFlowToRegion(location);
                if (region)
                    location.moveBy(region->topLeftLocation() + -parentLayer->renderBox()->topLeftLocation());

Removing the last two lines here fixes the bug.

It's curious how RenderBoxModelObject::adjustedPositionRelativeToOffsetParent has a very similar code:

                    RenderRegion* region = toRenderMultiColumnFlowThread(curr)->physicalTranslationFromFlowToRegion(referencePoint);
                    if (region)
                        referencePoint.moveBy(region->topLeftLocation());
