[GAMEPLAY] - [ITEM] - [TITANIC HYDRA] - Intentional Bug?

What I did that led up to the bug: 1.Bought Titanc Hydra 2.Bought Attack speed items 3.Activated Hydra before and during auto attacks with different champions 4.Found Bug that slow down champions Attack speed due to Hydra second prox animation

Results: Bug reported and hope that it's not intended as not mentioned in the item description and influence negatively on the Dps of champions that want to use Hydra's active while building Attack speed. Just to be clear i'm not mentioning the Aa reset, im mentioning the animation between the end of the first and the beginning of the second auto attack whenever Titanic Hydra is activated.

Titanic Hydra: "+450 Health +35 Attack Damage +100% Base Health Regen

UNIQUE Passive - Cleave: Basic attacks deal 5 + 1% of your maximum health as bonus physical damage to your target and 40 + 2.5% of your maximum health as physical damage to other enemies in a cone on hit. UNIQUE Active - Crescent: Cleave damage to all targets is increased to 40 + 10% of your maximum health as bonus physical damage in a larger cone for your next basic attack (20 second cooldown).

(Unique Passives with the same name don't stack.)"

I seen that this bug is old and has been reported several times, but never fixed, is it intentional to nerf campions that build Attack speed and the Hydra? If so shoudnt it be writen in the description of the item as it influence negativly the gameplay?
