gameplay- hit while recalling, did not cancel

howdy, i was playing as sona yesterday, i saw a recalling enemy with low hp.... i move to them, hit my q at the outer range near the end of the recall, my 2 magic hits from the q hit them, it did not cancel the recall, then as they finished recalling my empowered autoattack then finally traveled to where they were as they are disappearing, it disappears with them to travel back to the fountain and hit them and give me the gold proc from frostfange....

idk if this is suppose to be how it is from the new recall, it seemed like a bug

i do not know if it is repeatable

1. enemy begins recalling
2. q enemy recalling at edge of range as sona with empowered q near end of recall
3. hit with the faster 2 traveling magical components of the ability
4. hit the empowered auto near the end of the recall
