Updating data-gjs properties on label and form type results in weird behaviour

I'm applying the following settings to label data-gjs-type and on doing that some of the label tag are not visible anymore. Similar things happen while applying the properties to form

domc.addType("label", {
    model: defaultModel.extend({
      defaults: Object.assign({}, defaultModel.prototype.defaults, {
        removable: false,
        draggable: false,
        droppable: false,
        badgable: false,
        stylable: false,
        highlightable: false,
        copyable: false,
        resizable: false,
        editable: true,
        selectable: false,
        hoverable: false
      }
    })
  });
