I agree, happens to me all the time. The problem is that destroying a tab doesn't happen instantly, and you click again and again. Since the click is buffered, it will apply the action after the tab is closed. Safari feels much more thought out I have to say, but the feature/bug mentioned here seems just a result of full space tabs while in FFox/Chrome they are acting as fixed width. Rule of UI: count on and compensate for human errors and behaviour. Safari wins there for me (UI wise).
