When right-clicking on an AppWellIcon, the icon will become focused, which (presumably via style-changed) invalidates its current allocation, causing "icon.y" to return 0 until it has been reallocated, messing up our idea of where in the AppDisplay the icon is. Work around this by calling get_allocation_box() instead. https://bugzilla.gnome.org/show_bug.cgi?id=645162
