Yi alpha bug interaction with bard ult

As you can see here I attempt to Bard ult the rumble and yi but at the moment that my ult hits the yi goes into alpha.

Then after the yi does the alpha damage and lands on yasuo, he becomes targetable for a quarter to half second then the ult interaction happens.

I'm sorry I hit tab but I was just checking if yi actually had zhoynas or not.

Let me know if you are a bard player or yi player and if this interaction has happened to you in the past.
