I'm not sure if this is a bug, so I'm first posting this as a question. In the config option maniphest.custom-field-definitions I have a custom field like this:

{
  "cy:release-version": {
    "name": "Release Version",
    "type": "text",
    "search": true
  }
}

If I go to Maniphest -> Edit Query, it doesn't show me this custom field. However, if I change the type to "type": "int", the custom field is shown.

Am I doing something wrong? In the past this has worked.
