Terminal doesn't use custom bash profile when debugging

redirected here from closed issue https://github.com/microsoft/vscode/issues/80434
The bug appeared after one of few last updates.
When integrated terminal starts it uses custom profile (as expected),
but after python script is started it loads profile from ~/.bashrc

In my settings.json I have the following settings:

"terminal.integrated.shellArgs.osx": [
   "--rcfile", "/Volumes/DISK/projs/TechStuff/settings/profile"
],
"terminal.integrated.env.osx": {"HISTFILE":"/dev/null"},
"terminal.integrated.setLocaleVariables": false,

Expected behaviour

using custom profile (environment)

Actual behaviour

using standard profile (environment), after starting python script

Steps to reproduce:

1. Assign custom profile to integrated terminal settings.(and restart maybe)
2. Open page(tab) with any python script and open integrated terminal.
   (You can put string like echo 'bashrc loaded' in profile file to see it loads)
3. Check profile - it is cutom.
4. Debug python script (F5 or Debug -> Start Debugging) - it loads bashrc profile instead of custom
5. Check which profile is loaded (can use printenv command if you set different env. variables or check echo print as mentioned above) - standard profile loaded.

Bắt đầu bằng cách tái hiện sự cố với các cài đặt terminal.integrated.shellArgs.osx được liệt kê, một --rcfile tùy chỉnh và thao tác khởi chạy debug Python bằng F5. So sánh môi trường từ terminal tích hợp với môi trường sau khi debug bắt đầu. Được xem là hoàn tất khi tiến trình được khởi chạy bởi debug giữ nguyên profile tùy chỉnh đã cấu hình thay vì tải ~/.bashrc.
