Rapid Assault Skill Gem & Crescendo

I don't know of this is a bug or not but I noticed that the skill gem for Rapid Assault shows the tag, "Final Strike" in the gem text for when the attack finishes but the support "Crescendo" doesn't work with it even though it says it repeats "Final Strikes". It seems to me like these two should work together. If it's not intended then sorry for wasting time! It'd be cool though if they did work... :)



Rapid Assault:


Final Strike
Attack Damage: (100–312)%


Crescendo: Final Strike of Supported Skills can
be performed twice in succession

Fullfills every requirement, I also dont know why it should not work. Must be a bug.
