The only time this won't work is if it disappears before the time for autosave (may be a few seconds) so next time you write something look for a little flashing yellow 'autosave' thing that happens on the lower right hand corner of your reply box.
Just to test, write something and look at the right hand corner for say, five or six seconds and see if it flashes on and off quickly.
For example, mine autosaved this thing at least seven times while I was writing this.
