I've tolerated this for 2 years, and has no one filed this issue yet?

2年前就发现了这个问题，忍着等你们其他人提，但就是没人提，你们没人碰到这类问题吗？

SSH登录堡垒机，通过堡垒机进入其他子服务器，这种情况SFTP是用不了的，但是Termius支持的非常好，我想说是不是windterm该更新一下了？

竟然2年了，都没看到一条提出来关于此类的问题，真的忍不了了，我来提！！

Start by reproducing SFTP access through an SSH bastion, as described in the issue, and compare the behavior with a direct connection. Identify the relevant connection and SFTP entry points, then document the expected result and verify that transfers work through the intermediate server.
