Thanks for letting us know about this, @tokenflow. It appears to be a duplicate of #4122, which turned out to be due to an upstream bug. So unfortunately this will need to be fixed in VS Code itself (rather than the Python extension).

Already submitted this issue to VS Code team, they responded it is an extension issue !!

microsoft/vscode#74565 (comment)

What is the status of this if it is an extension? Is there something that can be done by users or is this use-case broken/no-fix at the moment?

Both the teams VSCODE and VSCODE-EXT saying its the other team issue !!

The issue I know about is still open upstream:

microsoft/vscode#38137

Also, the issue you referred to has been re-opened.
