Calling _super on a frozen object results in a violation of the freeze

[mixonic]

In 1.5, it was possible to:

var a = Ember.A([]);
var MyArrayMixin = Ember.Mixin.create({
  contains: function(){
    return this._super();
  }
});
MyArrayMixin.apply(a);
Object.freeze(a);
a.contains();

By 1.6, this raised an exception about modifying the frozen object. The exception is raised by __nextSuper, though __nextSuper was already in 1.5.

Replaces #5324 as a general case, could be addressed by #5430. May ref #5463.

Issue still exists in 1.8.0. @mixonic any updates?
