LIM - can't multiple click decorations over the menus labels

When you activate Locally Integrated Menus (LIM) on Ubuntu 14.04 Trusty Tahr, you can properly move a window even when menu is shown just as expected. However, when you try to maximize a window double clicking on the menu item shown on the decoration, it does not work. The menu is triggered instead. It properly works as expected if you double click an area after the menu items. The menu should be triggered only when a single click is made, not a double click, if this is possible to distinguish. The same goes on unmaximizing. If you try "triple" clicking the menu on an not-maximized window, it often do work maximizing it. That is not the expected behavior IMHO.
