python withPackages will reset/disable override

[Nambers]

Describe the bug

Python withPackages will reset/disable override of package.

Steps To Reproduce

Consider following nix scripts:

let
  pkgs = import <nixpkgs> { };
  myPython = ((pkgs.python311.override (oldAttr: {
        sourceVersion = {
          major = "3";
          minor = "11";
          patch = "1";
          suffix = "";
        };
      })).overrideAttrs(oldAttrs: 
        {
          src = pkgs.fetchFromGitHub {
            owner = "python";
            repo = "cpython";
            rev = "v3.11.8";
          };
        }));
  myPythonWithPackages = myPython.withPackages (pypkgs: with pypkgs; [pip]);
in
pkgs.mkShell {
  packages = [
    myPython
  ];
}

let
  pkgs = import <nixpkgs> { };
  myPython = ((pkgs.python311.override (oldAttr: {
        sourceVersion = {
          major = "3";
          minor = "11";
          patch = "1";
          suffix = "";
        };
      })).overrideAttrs(oldAttrs: 
        {
          src = pkgs.fetchFromGitHub {
            owner = "python";
            repo = "cpython";
            rev = "v3.11.8";
          };
        }));
  myPythonWithPackages = myPython.withPackages (pypkgs: with pypkgs; [pip]);
in
pkgs.mkShell {
  packages = [
    myPythonWithPackages
  ];
}

the first one will result in 3.11.8 but the second one is 3.11.9 which is the original one pkgs.python311 (w/o any override)

Expected behavior

Both of above scripts should result in a 3.11.8 python.
