[Gameplay] Syndra's W targets can die

Hello,

This morning, I wanted to try some new runes with Syndra against a bot, then I noticed a bug with her W. I reproduced it in the practice tool (Youtube link).

The bug, as you can see in the video linked, is that Syndra's W targets can die while picked. It seems to work only with minions aa, I tried to last hit a minion with my own aa, using W on it when it'll receive this aa, but he didn't died, same for turret's hit, it doesn't kill the target picked. And it seems like it can kill the target only quickly after picking it, I tried to flash out to extend the travel time of the aa, then the minion survived.

Not a really annoying bug that we'll often encounter, but still a bug to me.
