Radio button placement issue in Inno Setup license page

Question

I followed @Martin's answer here on how to create two license text pages using Inno Setup.

Reposting the code again for quick reference.

[Code]

var
  SecondLicensePage: TOutputMsgMemoWizardPage;
  License2AcceptedRadio: TRadioButton;
  License2NotAcceptedRadio: TRadioButton;

procedure CheckLicense2Accepted(Sender: TObject);
begin
  // Update Next button when user (un)accepts the license
  WizardForm.NextButton.Enabled := License2AcceptedRadio.Checked;
end;

function CloneLicenseRadioButton(Source: TRadioButton): TRadioButton;
begin
  Result := TRadioButton.Create(WizardForm);
  Result.Parent := SecondLicensePage.Surface;
  Result.Caption := Source.Caption;
  Result.Left := Source.Left;
  Result.Top := Source.Top;
  Result.Width := Source.Width;
  Result.Height := Source.Height;
  Result.OnClick := @CheckLicense2Accepted;
end;

procedure InitializeWizard();
var
  LicenseFileName: string;
  LicenseFilePath: string;
begin
  // Create second license page, with the same labels as the original license page
  SecondLicensePage :=
    CreateOutputMsgMemoPage(
      wpLicense, SetupMessage(msgWizardLicense), SetupMessage(msgLicenseLabel),
      SetupMessage(msgLicenseLabel3), '');

  // Shrink license box to make space for radio buttons
  SecondLicensePage.RichEditViewer.Height := WizardForm.LicenseMemo.Height;

  // Load license
  // Loading ex-post, as Lines.LoadFromFile supports UTF-8,
  // contrary to LoadStringFromFile.
  LicenseFileName := 'license2_' + ActiveLanguage + '.txt';
  ExtractTemporaryFile(LicenseFileName);
  LicenseFilePath := ExpandConstant('{tmp}\' + LicenseFileName);
  SecondLicensePage.RichEditViewer.Lines.LoadFromFile(LicenseFilePath);
  DeleteFile(LicenseFilePath);

  // Clone accept/do not accept radio buttons for the second license
  License2AcceptedRadio :=
    CloneLicenseRadioButton(WizardForm.LicenseAcceptedRadio);
  License2NotAcceptedRadio :=
    CloneLicenseRadioButton(WizardForm.LicenseNotAcceptedRadio);

  // Initially not accepted
  License2NotAcceptedRadio.Checked := True;
end;

procedure CurPageChanged(CurPageID: Integer);
begin
  // Update Next button when user gets to second license page
  if CurPageID = SecondLicensePage.ID then
  begin
    CheckLicense2Accepted(nil);
  end;
end;

However, for me, the radio buttons are overlapping with the license text editor (see image below)

Radio button overlapping with the license text

Is there any way to fix it?

Thanks.
