Disable highlightable on bold text

[tiborpino]

Is there a way to update defaults for built-in components? I have bold text inside element. All bold elements should have default highlighted: false. I tried this config but no success

    Editor.DomComponents.addType('text', {
      model: {
          defaults: {
            tagName: 'b',
            highlightable: false,
          }
        }
      });

I don't use any storageManager and elements b, i etc. are always highlighted. When I use storageManager local, element are ok and not highlighted.
