+++ This bug was initially created as a clone of Bug #584261 +++

In the patch for the bug that this bug blocks, we send out additional notifications that expose this.
The above description and the comment in http://hg.mozilla.org/mozilla-central/rev/63b9ba3664a0 sound very much like we'd want this in SeaMonkey as well.
