[GAMEPLAY] Yasuo EQ combo

I have seen this for a while now and I can't tell whether I am the only one who notices or if this bug is un-fixable. I decided to post this after witnessing it again in the one for all gamemode because I felt like it was about time. BTW, when I say yasuo's e-q combo, I mean the Sweeping blade -> Steel tempest combo which makes yasuo's q cast in a circle around him.

The bug: When yasuo has 3 stacks on his q, his next e-q combo might not deal damage. What I mean by this is that the enemy is still knocked up, but it deals no damage. I think it is not a visual bug either. I can still ult off of the knocked up champion, but the q does not deal any damage at all (the ult will deal damage). I have seen this happen to champions and minions, but I have not seen it on monsters mostly because I don't jungle with yasuo or I am right up close to the monster.

When the bug occurs: This occurs when the enemy you are hitting is right on the edge of your skill cast, so in this case, when the enemy is right at the edge of the circle made by yasuo's e-q combo. The enemy has to be RIGHT ON THE EDGE. This can occur quite often because people are usually running away from yasuo, making themselves right on the edge of the circle cast or when minions are scattered in a lane and you e-q off one minion to hit the entire wave.       Irrelevant or perhaps relevant information: I feel like this can happen on any number of stacks on his q, but it is unnoticeable since it does not deal any damage. If i remember correctly, this also occurred with steel tempest's whirlwind without the e-q combo but I haven't seen that happen anymore after the "on hit effects" change for the whirlwind (5.14). This is my first time reporting a bug, so please don't mind my format :[
