Current Behavior

When using the description property in a oneOf subSchema, it isn't rendered under the dropdown menu.

{
  "type": "object",
  "properties": {
    "plan": {
      "type": "string",
      "oneOf": [
        {
          "const": "vcluster",
          "title": "Virtual cluster plan",
          "description": "This is a virtual cluster plan."
        },
        {
          "const": "coab",
          "title": "Cloud-on-a-bench plan",
          "description": "This is a cloud-on-a-bench plan."
        },
        {
          "const": "kamaji",
          "title": "Kamaji plan",
          "description": "This is a Kamaji plan."
        }
      ]
    }
  }
}

Expected Behavior

We should see a text field under the dropdown selection menu that dynamically changes the description of the selected field, similar to how it works for objects :

{
  "type": "object",
  "oneOf": [
    {
      "title": "Small",
      "description": "Small plan",
      "type": "object"
    },
    {
      "title": "Big",
      "description": "Big plan",
      "type": "object"
    }
  ]
}
