Comment (by strk):

 The problem, like in #5709, is that lwgeom_get_bbox gets an approximaged
 bounding box from the serialized representation of the geometry:
 {{{
 +psql:test.sql:28: DEBUG:  [topo/lwgeom_topo.c:lwt_ChangeEdgeGeom:3569]
 BBOX of changed edge did not change
 }}}

 Paul, Regina: should we maybe stop reding that lamed-down box from the
 serialized representation when deserializing into LWGEOM ?
