I don't know if this is an issue with React or IE11 but when an the input initially contains an EN-dash (8211) it fires the change event.

ReactTestUtils.renderIntoDocument(
      <input type="text" value="zoink" readOnly={false} />
    );
    expect(console.error.argsForCall.length).toBe(1);
  });
  it('should have a this value of undefined if bind is not used', function() {
    var unboundInputOnChange = function() {
      expect(this).toBe(undefined);
    };
    var instance = <input type="text" onChange={unboundInputOnChange} />;
    instance = ReactTestUtils.renderIntoDocument(instance);
    ReactTestUtils.Simulate.change(instance);
  });
  it('should throw if both value and valueLink are provided', function() {
    var node = document.createElement('div');
    var link = new ReactLink('yolo', jest.genMockFn());
    var instance = <input type="text" valueLink={link} />;
    expect(() => ReactDOM.render(instance, node)).not.toThrow();
    instance =
      <input
        type="text"
        valueLink={link}
        value="test"
        onChange={emptyFunction}
      />;
    expect(() => ReactDOM.render(instance, node)).toThrow();
    instance = <input type="text" valueLink={link} onChange={emptyFunction} />;
    expect(() => ReactDOM.render(instance, node)).toThrow();
  });
  it('should support checkedLink', function() {
