It is not the same as Elusive Jump.

Sometimes when doing a burst, particularly after a jump, but not always, my dragoon will do a very long, broad-arcing backflip. There's no sound effect like there is with Elusive Jump. It doesn't always happen with the jump but seems to happen at random.

I was wondering if any dragoons who play Feast know what this is and what causes it. It made me backflip right into enemy territory last night and I just about punched a hole in the wall because it was absolutely unintentional. What's causing it?
