Disable symbol stripping for VSCode

The issue is based on Enable mandatory signature verification in Linux · Issue #239579 · microsoft/vscode · GitHub.

I have the following config for enabling VSCode and I’m still getting the issue mentioned on GitHub. Is there some way to check if the symbols were stripped or not so I can see if it’s even the same issue?

  programs.vscode = {
    enable = true;
    package =
      (pkgs.vscode.override {
        isInsiders = true;
        commandLineArgs = "--password-store='gnome-libsecret'";
      }).overrideAttrs
        (oldAttrs: rec {
          version = "latest";
          src = (
            builtins.fetchTarball {
              url = "https://code.visualstudio.com/sha/download?build=insider&os=linux-x64";
              sha256 = "";
            }
          );

          dontStrip = true;
          buildInputs = oldAttrs.buildInputs ++ [ pkgs.krb5 ];
        });
  };
