Wraith Ult not disjointed while inside Enchanter's Satchel

[AceVoid]

Ulted by Wraith while playing Pocket and using Enchanter's Satchel is meant to disjoint the ultimate projectile but in this match it stuck around where my character was meant to be while I was inside my satchel and caught me after I jumped out. See attached video
