They relay WM_RBUTTONDOWN as WM_LBUTTONDOWN in a first place in subclass
procedure so control never gets it:

--- TabBar.cpp ----
case WM_RBUTTONDOWN :    //rightclick selects tab aswell
{
    ::CallWindowProc(_tabBarDefaultProc, hwnd, WM_LBUTTONDOWN, wParam, lParam);
    return TRUE;
}
---

Wine's control sends NM_RCLICK notification after WM_RBUTTONDOWN (so it doesn't
in this case). Simple test with ControlSpy with default Tab behaviour shows
that NM_RCLICK is sent on mouse release, so after WM_RBUTTONUP.

Attached patch fixes this.
