Yasuo E-Q Knockup-bug 100% replication

Yasuo has many bugs, and many are a detriment to his play style, but the problem is that they are very hard to pinpoint exactly what the cause of these bugs are. Currently, I am working with a friend to determine the cause of yasuo's more infamous bugs, such as the inability to auto attack after ulting, or after casting an e-q combo. In our trials, the only conclusive bug that we 100% know how to reproduce is a bug involving yasuo's E-Q knock combo. Should we find success in figuring out exactly how to reproduce yasuo auto-attack after eluting bug, I will post it here.

E-Q Knockup Yasuo knocks-up enemies (both minion and champion), but it does not damage them. This occurs only on Yasuo's e-q combo, and the enemies have to be on the VERY edge of Yasuo's knock circle. This will not take long to reproduce, but it takes a little bit of practice to hit the minions or champions just on the very edge, but nonetheless the bug will occur 100% of the time under the correct circumstances. Reproduce:

1. yasuo's build does not matter, simply find a minors wave or champion, and prepare to dash.
2. use you e-q combo, and specifically attempt to get one or more of the minions/champions on the VERY edge of the the e-q knockup, and they will be knocked-up like the rest of the wave, but will not take damage. Do not get disheartened if this does not happen the first time you attempt it, eventually when you hit the enemies properly on the edge of the E-Q circle, they will be knocked-up, but the damage that your Q SHOULD of dealt will not be done. You can even use the audio to help you, you can hear the audio for Yasuo's knock triggering on the enemy, but the audio for his Q will play as though it hit nothing, even though the E-Q hit and knocked-up the minion.
3. After successfully positioning yourself and executing your E-Q combo, you should have 100% success in replicating the bug.

Here is an example, the Jax takes damage from yasuo's E, but does not take damage from the E-Q combo that clearly hit.
