【问题描述】：
当使用迁移工具 here 将新存储库导入 Github 时，有一个使用 Bootstrap 3 制作的漂亮而简单的反向进度条示例。 我正在尝试重现此进度条。 Here 是我迄今为止的成就，下面或here 是一个工作示例：
- 第一个例子是一个静态的反向进度条
- 第二个示例显示动画保留进度条
- 第三个例子是标准进度条
发生的情况是 reverse-progress 栏在更新百分比状态之前由于某种原因完全显示（可能是属性 background-image？），而常规 progressbar 工作正常。
进度更新功能UpdateUIReverseProgressBar出了什么问题？
