zigbee2mqtt not forming a mesh network

[kiwijunglist]

Problem: in mesh graph all devices either connect directly to the co-ordinator or don't have an arrow to anything in the map. However all devices seem to be functioning correctly when reporting status etc.

hass.io version: 0.84.1
zigbee2mqtt version: edge (latest version)

Co-ordinator: cc2531 (x1)
Routers: cc2531 (x2) & xiaomi zigbee plugs (x3)
End devices: mixture of mija & aqara door sensors and occupancy sensors.

Total devices: 22 (incl router / co-ordinator)

It is, but it's just not shown in the network map, see #652.
