[GAMEPLAY] Drowsy from Zoe E doesn't increase damage from Liandry's Torment

Drowsy slows enemy champions, so intuitively, it should cause to deal increased damage. However, it does not (refer to the clip). As you can see on the training dummies, each tick during drowsy deals 42-43 damage, and it is only once they fall asleep that it deals 71-72 damage. This appears to happen consistency, and independently of madness stacks.

Here is an additional clip on a bot, to show that it's not solely a training dummy issue: https://cdn.discordapp.com/attachments/449313836642729984/624676757626290179/9-18_NA1-3153722160_01.webm .

Reproduction:

1. Buy Liandry's Torment on Zoe.
2. Hit an enemy champion with her E.
