Drawing errors with TbMenu.dropup set to true
When TbMenu.dropup is set to true, menu is drawn incorrectly. The "arrow-corner" is still pointing up (like in menus opened down), while it should point down, toward parent menu object. And if such opened up menu has subitems, they are drawn in a complete mess -- background is somewhere else and many other drawing errors appears, making dropup option completely unusable (see attachment). Do you know if this is extension issue or whole Bootstrap works like this?
