I don't know that Position checks it's offset to see if it's valid.  Perhaps
this could be the problem (from RenderObject::createVisiblePosition):

        // Find non-anonymous content before.
        renderer = child;
        while ((renderer = renderer->previousInPreOrder())) {
            if (renderer == parent)
                break;
            if (Node* node = renderer->node())
                return VisiblePosition(node, numeric_limits<int>::max(),
DOWNSTREAM);
        }
