LAN tags subcollection missing

[ashkuren]

Tag subcollection is missing for /api/lans endpoint.
ManageIQ version: jansa-3.20210118183104_77bdc30
OPTIONS call to /api/lans:

{
    "attributes": [
        "allow_promiscuous",
        "computed_allow_promiscuous",
        "computed_forged_transmits",
        "computed_mac_changes",
        "created_on",
        "ems_ref",
        "forged_transmits",
        "id",
        "mac_changes",
        "name",
        "parent_id",
        "switch_id",
        "tag",
        "uid_ems",
        "updated_on"
    ],
    "virtual_attributes": [
        "href_slug",
        "region_description",
        "region_number"
    ],
    "relationships": [
        "guest_devices",
        "hosts",
        "lans",
        "miq_templates",
        "parent",
        "subnets",
        "switch",
        "taggings",
        "tags",
        "vms",
        "vms_and_templates"
    ],
    "subcollections": [],
    "data": {}
}

Tags can still be obtained by calling: /api/lans?expand=resources&attributes=tags
But when I try to set tags with POST to /api/lans/10000000000055/tags with body:

{
  "action" : "assign",
  "resources" : [
    { "name" : "/site/l2" }
  ]
}

The response is 404 Not Found.
