🐞 If two workspaces are open adding a new terminal tab opens to the wrong directory

### Description

If two workspaces are open adding a new terminal tab opens to the wrong directory

### To Reproduce

1. Open two projects
2. Open terminal utility on one window
3. Click add terminal tab
4. Notice it opens to other projects directory

### Expected Behavior

Each window should open terminal tabs to their own directory

从终端工具的 add-terminal-tab 操作开始，跟踪每个工作区窗口如何提供其工作目录。使用两个已打开的项目重现该问题，然后验证新标签页使用创建它们的窗口的目录。
