miss button on pop up window due to notification server limiation

Hi,

This issue is related with emacs and ubuntu gnome. In emacs if we eval below code:

(progn (require 'notifications)
(notifications-notify
:title "only show aa bb cc"
:body "d e are missing"
:timeout 10
:urgency :normal
:actions '("a" "aa" "b" "bb" "c" "cc" "d" "dd" "e" "ee")
:on-action (lambda (id key) (message "id: %s key: %s" id key))))

There should be 5 buttons shown on pop up window, "aa", "bb", "cc", "dd", "ee". But it only shows three button "aa", "bb" and "cc", the other two button "dd" and "ee" are missing.
I have issue this bug to emacs https://debbugs.gnu.org/cgi/bugreport.cgi?bug=56834, but they conclude this is notification server limitation, so I suppose I should issue the bug here, hope issue can be solved here.
