Yup, apparently the snare exists so that the game engine can make gap closers fire and hit more reliably and bug out less.
And yes, we're apparently stuck with it even though it's highly abusable.

Gap closer snare ignores all types of immunity - it's not a bug just working they way they intend it. It's a different matter whether it should work that way.
