【报Bug】uniapp previewImage预览图片时删除图片，预览界面图片仍在

详细问题描述

使用uni.previewImage接口创建图片预览后，使用该api自带的长按操作删除当前图片后，在图片预览界面中，该图片依旧在，但是在imgList中其实已经被删除了。
问题就是，删除的图片并未及时反映到预览界面。

let isContinue = await this.isFullImg();
if (!isContinue) {
return;
}
}
uni.chooseImage({
count: this.countIndex - this.imageList.length,
success: res => {
this.imageList = this.imageList.concat(res.tempFilePaths);
},
fail: err => {}
});
},
isFullImg: function() {
return new Promise(res => {
uni.showModal({
content: '已经有9张图片了,是否清空现有图片？',
success: e => {
if (e.confirm) {
this.imageList = [];
res(true);
} else {
res(false);
}
},
fail: () => {
res(false);
}
});
});
},
// 预览图片
previewImage: function(e) {
var current = e.target.dataset.src;
uni.previewImage({
current: current,
urls: this.imageList,
// 长按删除图片 idx为图片索引
longPressActions:{
itemList: ['删除'],
success: res => {
if (res.tapIndex == 0) {
this.imageList.splice(res.index, 1);
}
},
}
});
},

}  

};

[期望]

期望能在预览longPressActions操作的时候删除当前索引的图片能及时反馈到预览组件中，
