subform `nomin` displays, even though it's subform is set to `<occur max="-1" min="0" />`

_bindOccurrences(formNode, matches, picture) {
    
    
    let baseClone;
    if (matches.length > 1) {
      
      baseClone = formNode[$clone]();
      baseClone[$removeChild](baseClone.occur);
      baseClone.occur = null;
    }
    this._bindValue(formNode, matches[0], picture);
    this._setProperties(formNode, matches[0]);
    this._bindItems(formNode, matches[0]);
    if (matches.length === 1) {
      return;
    }
    const parent = formNode[$getParent]();
    const name = formNode[$nodeName];
    const pos = parent[$indexOf](formNode);
    for (let i = 1, ii = matches.length; i < ii; i++) {
      const match = matches[i];
      const clone = baseClone[$clone]();
      parent[name].push(clone);
      parent[$insertAt](pos + i, clone);
      this._bindValue(clone, match, picture);
      this._setProperties(clone, match);
      this._bindItems(clone, match);
    }
  }
  _createOccurrences(formNode) {
