发现个疑似BUG

当listview里的item数量比较少，listview不需要上下滚动的情况下，这时候左滑删除item后会导致剩余的item无法侧滑删除，必须等待一段时间，可能数十秒后才正常。

Start by reproducing the issue in SwipeMenuListView with a ListView containing only a few items, so no vertical scrolling is needed. Delete one item by swiping left, then check whether the remaining items can be swiped immediately or only after a delay. Done means remaining items remain swipeable without waiting after deletion.
