Why revalidation on mount even if cache was updated in fractions of second before

[pke]

I am filling up the cache of a useProductDetail hook after a search hook performed using cache.set(productKey(id), product) but when the useProductDetail hook is used, it still revalidates and hits the server again although the cache was just updated.

Sure I can set revalidateOnMount to false but that brings other undesired side effects.

Even after one year I am still unclear on the inner workings of swr in such situations.
