No buttons in modeless CXTPPropertySheet

Is there a reason why buttons aren't created in a modeless CXTPPropertySheet? I made a modal CXTPPropertySheetDlg modeless and all buttons (OK, Cancel, Apply) are gone.
A further look in the CJ code shows:

BOOL CXTPPropertySheet::CreateButtons()
{
  if (m_bModeless && !IsWizard())
    return TRUE;

Why that?


A quick workaround is:

int CMyModelessPropertySheetDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
  m_bModeless = FALSE;

  if (CXTPPropertySheet::OnCreate(lpCreateStruct) == -1)
    return -1;

  m_bModeless = TRUE;

  return 0;
}
