DropDownMenu running onChangeValue despite no changes

If you click on the DropDownMenu and do not select anything or select the same value it will run the onChange function despite no changes causing unnecessary dispatches/rerenders when using redux.

I tried to remedy the issue by preventing any actions if the value is the same as currently selected:

handleValueChange = val => {
  if (this.state.selectedValue !== val) {
    this.setState({ selectedValue: val })
  }
}
<DropDownMenu
  defaultValue={this.state.selectedValue}
  values={this.state.values}
  onChangeValue={this.handleValueChange}
/>

The problem with this approach is that while it does prevent unnecessary onChangeValue runs it locks the component in a valueless state when you toggle the component and click outside the options. Pitfall of not using <select>/<option />?
