Azir Shaco ULT /interactionBug

Good day, I am not sure if this is meant to be the correct interaction between Shaco's ult and azir's ult wall but in regards to azir's ult interacting with shaco's clone. I found that When azir ult's a shaco clone the clone does not get pushed back by the wall instead azirr's ult will only interact with the real shaco pushing him back bu the ult goes right through the clone. If i could get some feed back as to if this is the intended way these 2 ults should interact it would be greatly appreciated.

side note: it pushes back minions so i would assume shaco's clone should get pushed back also.
