the second part of the patch can't obviously be correct.
That message id is an application internal one, used to trigger next (menu)
action - hence you won't find any related information on the internet.

The reason why this patch "works" is because this internal message is *posted*
every time after the app sends WM_CANCELMODE to the owner window of the popup -
which ought to dismiss it.
That WM_CANCELMODE message is sent using SendMessage() which directly calls
into window proc - not seen by menu tracking message pump. 

Wine's default WM_CANCELMODE handler doesn't call EndMenu() when the receiving
end is a child window/control (WS_CHILD set, popup owner -> toolbar).
EndMenu() should force the menu tracking message pump to exit.
I'm curious why this restriction to non child windows exists here.
Any parent window/control which owns the active menu can have such style.
