Usage in conjuction with `DC_Folder`

[bytehead]

I try to use tags for tl_files. The values get stored on the database (I can see them), but won't be shown after load of the edit view.

I registered a load callback on this particular field and the $value is an empty array [].

Weird is also, that the activeRecord on the DataContainer in that callback doesn't have the property set:

[Contao\FilesModel](file:///vendor/contao/core-bundle/contao/models/FilesModel.php#L93) {#11538 ▼
  #arrData: array:19 [▼
    "id" => 254
    "pid" => b"\x12?@*³ä\x11ðœƒ\v)ãÁZ\x1A"

  ]
  #arrModified: []
  #arrRelations: array:1 [▼
    "associationTags" => array:4 [▼
      "table" => "tl_cfg_tag"
      "field" => "id"
      "type" => "haste-ManyToMany"
      "load" => "lazy"
    ]
  ]
  #arrRelated: []
  #arrEnums: []
  #blnPreventSaving: false
}

Is this a known limitation?

The same field definition (in contao/dca/tl_files.php) works as expected in contao/dca/tl_content.php.
