Description
说明
cascader 组件无障碍支持还遗留的问题如下：
- 上一层【被选中的】选项能获取焦点（点击后切换到下一层级，但上一层【被选中】的那一项还能被选中）
- 最后一层级，点击后无法无法关闭
因一时间未找到解决办法，所以先行合并了前置 pr #1657 ，以完成前置支持，在这里重新提一个 issue 来记录，同时也希望能有社区大佬给解决一波！

Research direction
Start by reproducing the cascader accessibility issues described in the issue: whether the selected option in the previous level can still receive focus or be selected, and whether clicking an option in the final level closes the component. Done means both focus/selection behavior and final-level closing work correctly, with the existing accessibility support preserved.
