我们有一个带有一些条目的 ListView（在我们的测试用例中为 205 个条目），当您快速滚动列表时，JS 线程 fps 有时会从 60 下降到大约 20，然后 TouchableOpacity 元素将变得无响应（就像所有其他 React 元素一样）。UI 线程 fps 保持在 60 并在列表中滚动仍然可能，但 Touchable 需要一些时间才能再次响应。
看起来 react 正在为事件创建某种队列，并且滚动会向其中添加事件，而 Touchable 上的触摸事件必须等待所有其他“不重要”事件得到处理。
我们正在使用 React 版本 15.4.2 和 React-Native 版本 0.40.0。
我们可以在 LG Nexus 5X 和三星 Note 4 上几乎不断地重现该问题，但不幸的是，模拟器中没有（x86 似乎跑得快而手臂慢了）。
这是我们可以重现问题的测试组件。
