The problem here is that RenderMultiColumnFlowThread::mapFromFlowToRegion doesn't add the layer offset when computing the translation offset despite the fact RenderMultiColumnSet::columnTranslationForOffset returns an offset from the layer's top left corner. This is in contract to RenderLayer::collectFragments. It calls RenderMultiColumnSet::collectLayerFragments, which also returns an offset from the layer's top left corner, but it adds the layer offset so everything is fine there.
