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.

まず、記載されている terminal.integrated.shellArgs.osx 設定、カスタムの --rcfile、および F5 を使用した Python のデバッグ起動で問題を再現します。統合ターミナルの環境と、デバッグ開始後の環境を比較します。デバッグによって起動されたプロセスが ~/.bashrc を読み込むのではなく、設定されたカスタムプロファイルを保持すれば完了です。
