Armor Stands will disappear if splash potions of harming II are used near or on them.

I was healing my Zombie Pigman within my house with a splash potion of harming II, and the splash caused the armor stand holding my fully enchanted golden armor and sword to be essentially deleted form the game permanently as the armor stand has completely disappeared. 

Not a huge deal easy to replace that stuff. But harming II (Harming 2) splash potions should not do this if I am correct.

I have experimented with other empty stands and the effects are the same.
