[UIXPress] UI bug in compact mode

Hello,

There is also a UI problem with sub-menus in compact mode. They are displayed out of screen (browser) if it’s a won menu icon. This problem is also general to the entire plugin. Many menus or submenus appear off-screen when the icon or menu item to which they are attached is close to an edge of the browser window.

I hop this could be solved. Than’s !
