Default value of nested Text field inside Set inside Repeater

Can I set the default value of the Text field in this case?
I am having a Text field in a Set inside a Repeater.
It does not work for me. No default value is filled.
Here is my stripped JSON:

 {
  "fields": [
    {
      "name": "events",
      "type": "set",
      "label": "My events",
      "options": {
        "display": "limit",
        "fields": [
          {
            "name": "limit",
            "type": "text",
            "label": "The limit",
            "options": {
              "default": "0",
              "pattern": "^([0-9]+)$",
              "required": true
            }
          }
        ]
      }
    }
  ]
}

should be possible now in the current next branch
