No, the definition says ‘especially one that is short-lived’. It means that things that are not short-lived can still be fads. It’s clearly an optional attribute. The key attributes are ‘intense’, ‘widely shared’.
Well, it depends what dictionary you consult. Can you give an example of a long-lived thing that would be widely considered a fad?
There are fads that have persisted over a longer term by coming in and out of fashion, like say bell-bottom pants. But I can’t think of something that would be widely considered a fad that has stayed in fashion for decades.
