Disable open menu tracking outside of Windows

Tracking whether or not the menus are opened is necessary on Windows since menus stop
the main loop. This is not necessary on other platforms. In particular, on Mac, we do
not get a `wxEVT_MENU_CLOSE` event when opening a dialog from a shortcut, resulting in
the menu status tracking being incorrect.

Fixes #1348
