Subject: [PATCH] popupMenu: block input events when menu is closing

At the moment gnome-shell can get really confused if a menu is
fading out and gets clicked.

It can lead to mouse pointer input getting stuck until the shell
is restarted.

This commit addresses the problem by ignoring input events that
come in when the menu is closing.
