UI freeze break request for GNOME Shell

[Florian Müllner <fmuellner gnome org>]

Hey!

I am really sorry for this, but I'd like to request another freeze
break for GNOME Shell. As you may know, notifications in the message
tray now spot a small close button, which may be used to dismiss the
notification. While we managed to match the mockups pretty well, the
designers did not agree at all with the implemented behavior of the
button once they actually were able to try the code[0] - which was
fairly late unfortunately.
Yesterday we finally managed to land the requested changes to master,
but unless we push out a 3.6.2 release including those, we will give
users six months to become accustomed to the "wrong" behavior, making
the change far more painful than necessary.
I have done a quick check on the documentation, it does not look like
either behavior is currently documented; in terms of code, the changes
are very small and unintrusive. So my only concern is really to
irritate users by pushing a change like this in a stable series, which
is of course far from ideal. Still, I believe it will be much more
disruptive at a later point, so including it in a 3.6.2 release
constitutes the lesser evil in my opinion.

Thoughts?

Florian
