A face merge may keep one of its faces' names (Merge::into, model FaceMerge::into): absorbing a tiny face leaves the neighbour by its own name, so sets on it still select it. Shape::absorbing_neighbour finds the face a tiny one shares the longest edges with. geometry.face.absorb absorbs one face (into a named or the best neighbour) or, from_check, every small and sliver face the last geometry.check marked; check marks now carry the small face they found.
