"The editor is actually provided by Firefox. There is a bug report to add undo/redo key support - https://bugzilla.mozilla.org/show_bug.cgi?id=683172 . If this isn't fixed by the time Firefox 8 is released, I will implement a workaround."
Even if it is true, the v1.2.1 has different editor, not the best, but at least it has undo/redo. v1.2.3 still has the same buggy editor. And btw the previous icon was way much better.
