获取信息流的广告了，但是渲染监听没有执行，是为什么

获取广告成功: {"ads":[{"imgWidth":0,"imgHeight":0,"provider":"ks","sourceId":0,"id":13535887,"showMode":"unknown"},{"imgWidth":0,"imgHeight":0,"provider":"ks","sourceId":0,"id":264421660,"showMode":"unknown"},{"imgWidth":0,"imgHeight":0,"provider":"ks","sourceId":0,"__id":74117413,"showMode":"unknown"}]}
