This used to be the case. You could join an instance while your fate didn't finish yet and you'd simply receive your fate reward after you come back from your duty (failure reward as well).

This was back in ARR and I'm not sure when or why they changed this (would love to know). Really frustrating right now if your duty pops in the middle of a fate.
