divs like `BDTLL_feedback` coming from nowhere

I’m trying out the RNW (It’s awesome that you are implementing it!) and having some issues with some divs blocking my UI.

I think that the top one comes from the react-navigation header - even thought I have done:

export default class MenuScreen extends PureComponent {
  static navigationOptions = {
    header: null,
  }
...

Hey thanks for the report. Still working on react-navigation support so it may be a little bit buggy.
