Master Yi Bug
I noticed that in Patch 8.21 there were a couple bug fixes revolved around Auto attacks, specifically the Nunu bug fix, "Nunu & Willump's basic attack no longer cancels if Call of the Freljord expires during the attack's wind-up".
I wanted to point out that Master Yi has a similar 'Bug/Mechanic' with his Auto Attack and his passive, double strike. If Master Yi Auto Attacks as Double Strike expires, it cancels his Auto Attack. Albeit rare, it can have a detrimental impact upon the game.
