We purge it [here](https://github.com/facebook/react/blob/b11540ccb2321aeb7259fcf0b3a38aeeea35231d/src/isomorphic/ReactDebugTool.js#L88-L89) but this code doesn’t run because of the [early exit](https://github.com/facebook/react/blob/b11540ccb2321aeb7259fcf0b3a38aeeea35231d/src/isomorphic/ReactDebugTool.js#L53-L57).

Need to fix this and add a test case to make sure we don’t regress on it.

var actualHistory = ReactNativeOperationHistoryDevtool.getHistory();
    expect(actualHistory).toEqual(expectedHistory);
  }
  describe('mount', () => {
    it('gets recorded for native roots', () => {
      var node = document.createElement('div');
      ReactDOM.render(<div><p>Hi.</p></div>, node);
      var inst = ReactDOMComponentTree.getInstanceFromNode(node.firstChild);
      assertHistoryMatches([{
        instanceID: inst._debugID,
        type: 'mount',
        payload: ReactDOMFeatureFlags.useCreateElement ?
          'DIV' :

    });
