Mutter bug for attached dialogs not attaching because of stacking is:

 https://bugzilla.gnome.org/show_bug.cgi?id=632007

There was a patch in there, but it has various issues - and
this points out an additional problem beyond what is noted there - if
that patch was applied, the dialog would have been been popped up
underneath, next to it's parent, but that would have happened after
Mutter already decided that it didn't need to "focus stealing prevent"
the dialog so you'd just have gotten no notification.

We need either to put the parent next to the dialog, which would cause
everything to pop to the front. Or we need to focus stealing prevent
the dialog - so you'd see "PackageKit is ready" in the notification
area.

To me the right thing here would be a notification - we don't want to
say "you can't do anything else until you restart", but rather "you
urgently should restart".
