React Native TabBarIOS "More …” Button Crashes

When I add more than 5 tabs to my tab bar a “More …” button appears in place of the overflowing items. When that button is clicked in my iPhone 6s emulator it crashes saying that the tab index is out of bounds of the array.

To REPRO .... I have a new v0.22 project. Here is my index.ios.js which crashes when the “More …” button is clicked...
