Kalista Guardian Angel AA Bug

Basically what happens is once I reach full build on Kalista (Berserker's Greaves, Bloodthirster, Hurricane, Botrk, Last Whisper and GA) I go out to fight like normal but when I "die" and the guardian Angel procs it put's me into stasis but my AA's keep going off. Causing the very confused me to wreck the faces of the equally confused enemy team... and then emerge from GA effect just like I normally would... I haven't tested this in ranked (only in normals) and will not be purchasing GA in ranked till this is fixed. In my opinion this is a particularly game breaking bug. At one point i Speculated that it was triggered when I used kalista's passive, but i haven't been able to reproduce the results every time and they are usually on accident. I will do some further testing on my own to find out exactly what triggers it, and post any info i find back here.
