Popup drop-down menu contains extra empty spaces at beginning and occupies whole screen when items in popup reaches the height of display device


Steps to reproduce:
1) Open www.google.com in MiniBrowser or GtkLauncher and click on advance search link on top right or goto
   http://www.google.com/advanced_search?hl=en
2) select language combobox

Observation 
* empty lines are seen at the beginning once scroll down and scroll up these lines are gone
* popup window occupies the whole screen
(screenshot attached)

RCA: As push_in is set to true for callback GtkMenuPositionFunc gets called on gtk_menu_popup 
GTK+ is trying to push the window into the visible area when 
part of the menu is outside the monitor (see http://developer.gnome.org/gtk3/3.1/GtkMenu.html#GtkMenuPositionFunc) 

Setting push_in to false will fix this issue. (No idea if this impacts other use-cases ?)

Sorry. I missed a few other things here. The first line should be the bug title. All stenences should start with a capital letter and end with a period. I'll fix this and land it.
