Label name with `undefined` when the workspace is not named

[yiliang114]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: code-oss-dev 1.75.0 05e1981
• OS Version: Mac os 12.2.1 (21D62) intel

Steps to Reproduce:

1. git clone the vscode latest source code.
2. Use cmd + shift + b keybinding to start the development process. (Core - Build and Ext - Build).
3. Prepare a simple file system extensions such as vscode-web-playground and use ./scripts/code-web.sh --extensionDevelopmentPath=LocalFileSystemPath . Execute ./scripts/code-web.sh . to start VS Code Web. It should be noted that the second parameter is ., Maybe this should be the reason why the workspace is an empty file name.
4. When the web is started, if no accident occurs, the workspace will open an empty name but the actual data of the file tree is the current code warehouse, just like in the screenshot.
5. Open a few files casually, either in the root directory or in a folder at any level, and you will find that the undefined is carried in the label.

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.74.3. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

When the workspace is not named, it is automatically set to Test Files, After debugging, I found that there is no separator at this time, which leads to the error of label name.

@yiliang114 can you give more details around how to reproduce, specifically:

Prepare a simple file system extensions such as vscode-web-playground

Where is that code?

@bpasero Thank you for your prompt reply. Originally, vscode-web-playground referred to https://github.com/microsoft/vscode-web-playground. I thought I had to debug the file system extension to reproduce this problem, but it is not needed now!

I just tried it again and found it didn't need to be so complicated. The third step is to execute ./scripts/code-web.sh . directly, there is no need to carry extensionDevelopmentPath.
