Research direction

Start with the Upload component and reproduce the issue using listType="picture-card", fileList limited to one item, and an auto-height parent. Confirm that adding the image does not cause a temporary height change, and add or update coverage if the repository has a relevant test entry point.

Description

比如下边这个例子，如果父容器是高度自适应的话，添加图片时高度会突变一下。

<Upload
      action="/api/file/upload"
      listType="picture-card"
      onChange={onChange}
      fileList={fileList}
    >
      {fileList.length < 1 ? (
        <div>
          <Icon type={loading ? 'loading' : 'plus'} />
          <div>上传</div>
        </div>
      ) : null}
    </Upload>
