Multiple code editor tabs ( read only ), each tab getting created every time you step into the code

[peddadap]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.96.2
• Electron: 32.2.6
• ElectronBuildId: 10629634
  -Chromium: 128.0.6613.186
  -Node.js: 20.18.1
  -V8: 12.8.374.38-electron.0
  -OS: Darwin arm64 23.4.0
• OS Version: macOS Sonoma

Steps to Reproduce:

1. Install VSCode version above
2. Install ms-python.python-2024.23.2025011101-darwin-arm64
3. Install ms-python.debugpy-2024.15.2024121701-darwin-arm64
4. ms-python.vscode-pylance-2024.12.1
5. github.copilot-chat-0.23.2
6. github.copilot-1.256.0
7. mini-conda
8. any python project -- open workspace folder
9. Go to tests and open up any unit-test
10. Put a break point and start debugger
11. Vscode opens up a new Tab { read-only} for the selected unit test
12. As you start stepping in , FOR EVERY STEP IN while debugging VSCODE keeping opening up new code editor

I'm attaching my launch and setting files, I'm not sure what is causing multiple tabs to open up like this, it is difficult to code and debug with various tabs that keep on opening

Also, a noticeable change in the latest and pre-release ( which I tried ) is unable to put break-points as the code editor ( tab) is read-only making debugging extremely painful, please see the screenshots, very easy to produce

Thank You!

I have very minimal extension, in fact I ended up re-installing the entire vscode studio with the listed extensions

/extPython

Looks like microsoft/debugpy#1736

It looks like this is caused by the Python extension. Please file the issue to the Python extension repository. Make sure to check their issue reporting template and provide them relevant information such as the extension version you're using. See also our issue reporting guidelines for more information.
