textNoElement not working

I am trying to update the textNoElement of the Style and TraitManager, but it does not seem to be working.

let editor = grapesjs.init({
  container: '#gjs',
  traitManager: {
    textNoElement: 'Hello Trait Manager'
  },
  styleManager: {
    textNoElement: 'Hello Style Manager',
  }
});

See the result here: https://jsfiddle.net/zrobkL80/5/

Also the default StyleManager sectors disappear, any suggestion on what I am doing wrong? I am using the the latest GrapesJS version (0.15.10).
