[GAMEPLAY] Akali ult stacks no longer visible as buff

As of a certain patch (I'm assuming 4.21, though I don't recall the last time I played with an Akali before today, and was not aware of this bug until today), Akali's buff icon that indicates the amount of ult charges she has stockpiled is no longer visible. She can still view her stacks by looking at her R in her ability tray, but her opponent has no way of knowing how many stacks she has available.

Steps to reproduce:

1: Queue up as Akali, or, alternatively, queue up against an Akali 2: Reach level 6 and put a point into your ult 3: Look at your buff bar and see no indicator

I first noticed the bug while laning against an Akali, and then played my next game as Akali in order to confirm it. The indicator was not visible on my buff bar in either game. This bug buffs Akali by eliminating a key element of counterplay; her opponent can no longer accurately gauge how much of a threat she poses, as they no longer have access to her number of ult stacks.
