Now I understand that it is wrong place for this test. I've removed it. The idea is that Global scope does not contain variable 'arguments', and access to the 'arguments' from global scope should lead to ReferenceError. Current test is executed in JSC app where arguments is empty array.

See line below. Without this change, but with current patch - arguments will start contain values of singleFireEventListener instead of values that is passed during wrappedCallback invocation.</pre>
