elment-ui el-image 设置initial-index失效 导致无法改变图片预览顺序

    <div>
        <el-image
          ref="imageEnlargeRef"
          style="width: 1px; height: 1px; position: absolute; opacity: 0"
          :src="url"
          :preview-src-list="getPreviewImages(3)"
        ></el-image>
     </div>



    getPreviewImages(index) {
      var imgList = [...this.srcList]
      console.log(index, 'imgList')
      if (index === 0) return imgList
      var start = imgList.splice(index)
      var remain = imgList.splice(0, index)
      console.log('start.concat(remain)', index)
      return start.concat(remain)
    }
