EarlGrey：由于下面的闲置资源很忙，因此无法执行阻止

Question

我运行了以下命令，它说无法执行阻止，因为下面的空闲资源很忙。

EarlGrey.select(elementWithMatcher: grey_accessibilityLabel("First Label")).atIndex(0).perform(grey_tap())

EarlGrey.select(elementWithMatcher: grey_accessibilityLabel("Second Label")).perform(grey_tap())

第二个标签位于顶部的导航栏上。点击该按钮屏幕即可滑动。

错误追踪：

我尝试通过将kGREYConfigKeyDelayedPerformMaxTrackableDuration的值更改为 threshold - 1 但没有进展来解决此问题。
