Interrupting Recall

Potential bug: I threw my Q as Lux towards a recalling enemy Kled and from the sounds of it, he still recalled even though I hit him with my Q.

Situation: I was playing One-For-All as Lux and enemy Kled. The Kled was recalling beside their first turret and I threw my Q then ran away, thus covering Kled in the Fog of War. I didn't see it hit him but I threw it, in my opinion, in his precise direction so it should have hit him. Then in another post in the bug board, I can still hear Gnar's recalling animation sound still going in the Fog of War and eventually, when I heard the sound effect as when you successfully recalled, I checked and he was gone.

Thoughts: Shouldn't it have interrupted Kled's recall when I hit him with Lux's Q? since it damages and roots Kled.

Additional detail: Kled just began recalling when I threw my Q as Lux and ran away, so it wasn't one of those situations where it was just too late when Kled managed to recall while Lux's Q was travelling towards Kled.
