Menu won't draw.

The menu added to a window won't draw when a skin is active. I have debugged and see CXTPSkinManagerSchema::CalcFrameBorders is called but it isn't calculating any width. All the relevant menu methods seem to get called. The class being used for the window is CXTPSkinObjectApplicationFrame.

Here is the minimum code:

static const TCHAR s_szAddInManagerDialogClass[] = TEXT("AddInManagerDialogClass");
static const TCHAR s_szAddInManagerMenuText[] = TEXT("Item 1");
static const UINT s_nAddInManagerMenuItem = 1001;

  HWND hDialog;
  WNDCLASSEX wc = { 0 };
  wc.cbSize = sizeof(WNDCLASSEX);
  wc.lpfnWndProc = AddInManagerWndProc;
  wc.hInstance = GetModuleHandle(NULL);
  wc.lpszClassName = s_szAddInManagerDialogClass;
  wc.cbWndExtra = DLGWINDOWEXTRA;
  if (!RegisterClassEx(&wc) && GetLastError() != ERROR_CLASS_ALREADY_EXISTS)
  {
      return HRESULT_FROM_WIN32(GetLastError());
  }

  hDialog = CreateWindowEx(WS_EX_CLIENTEDGE, s_szAddInManagerDialogClass, TEXT("Dialog with menu"),
    WS_OVERLAPPEDWINDOW | WS_VISIBLE,
    100, 100, 500, 300, NULL, NULL, GetModuleHandle(NULL), NULL);
  if (!hDialog)
  {
      return HRESULT_FROM_WIN32(GetLastError());
  }

  HMENU hMenu = ::CreateMenu();
  HMENU hSubMenu = ::CreatePopupMenu();
  AppendMenu(hSubMenu, MF_OWNERDRAW, s_nAddInManagerMenuItem, s_szAddInManagerMenuText);
  AppendMenu(hMenu, MF_POPUP, (UINT_PTR)hSubMenu, TEXT("Menu"));

    SetMenu(hDialog, hMenu);
    DrawMenuBar(hDialog);

If I turn off the skin (I added code to draw the menu items to make sure it wasn't a black on black issue:
