Blue Buff Disappears Entirely

So, I was watching my buddy smurf with Jungle Twisted Fate, and he got executed by Blue Buff. The thing was, his auto attack was mid flight when he died, so the buff died after he had been executed. The buff disappeared despite the change in S5 to prevent executions from stealing your buffs.

While it doesn't really impact any level of play (besides pre-30 and Bronze), I still felt obligated to share the experience.
