I think it is similar to someone (read fish) calling one bet, then realizing it was raised, and taking their bet back because there was no action behind them (because I am nice and don't act unless the action before me is correct). But a straddle is slightly different because it has to be blind to get the added 'benefit' of acting last, but before any cards are dealt, I would easily allow it to be brought back, because jokingly straddling is a part of my act...
