containers-by-image table mode only shows one host

[rade]

The same container image can reside (and by used) on multiple hosts. This is reflected in the containers-by-image report structure, which contains multiple parents for the host topology:

    "memcached;<container_image>": {
     ...
      "parents": [
        {
          "id": "ip-172-20-1-136;<host>",
          "label": "ip-172-20-1-136",
          "topologyId": "hosts"
        },
        {
          "id": "ip-172-20-2-118;<host>",
          "label": "ip-172-20-2-118",
          "topologyId": "hosts"
        },
        {
          "id": "ip-172-20-2-90;<host>",
          "label": "ip-172-20-2-90",
          "topologyId": "hosts"
        },
        {
          "id": "ip-172-20-3-251;<host>",
          "label": "ip-172-20-3-251",
          "topologyId": "hosts"
        },
        {
          "id": "ip-172-20-3-52;<host>",
          "label": "ip-172-20-3-52",
          "topologyId": "hosts"
        },
        {
          "id": "ip-172-20-3-76;<host>",
          "label": "ip-172-20-3-76",
          "topologyId": "hosts"
        }
      ],
...

And indeed that is what gets shown in parents area at the top of the details panel. But not in the 'hosts' column of the table view, which only shows a single host:
