"user32: Move the auto radio button group logic from BM_SETCHECK to WM_LBUTTONUP handler.
    This patch also changes the logic to get the control style with WM_GETDLGCODE
    instead of GetWindowLong to make the message test pass.
    "
    by Dmitry Timoshkov.
    See bug report https://bugs.winehq.org/show_bug.cgi?id=42010

- (ReactOS-only) Fix also the corresponding logic in COMCTL32.
