[Bugs] The "Changes" panel no longer shows any dropdown to choose between Committed/...

**Mood:** 😔
**Category:** Bugs

The "Changes" panel no longer shows any dropdown to choose between Committed/Uncommitted/Latest, and as a result there's literally 0 visible changes now because the working tree is clear. Meaning it's impossible for you to actually read and review the previous commits and changes that were made in this worktree/branch.

在 Windows 10 上从 /chat 路径使用 GitHub app v1.0.16 重现该问题，确保 working tree 干净且存在之前的提交。检查 Changes 面板及其 committed、uncommitted 和 latest 视图；当 working tree 干净时下拉菜单可见，并且可以查看之前的更改，即表示完成。
