                if ((testString === FUNCTION_WRAPPER || testString == BROWSER_TOOLS)) {
                    nativeDelegate.apply(target, args);
                    return false;
                }
            }
            catch (error) {
                nativeDelegate.apply(target, args);
                return false;
            }
        }
        else {
            var testString = delegate.toString(); 
            if ((testString === FUNCTION_WRAPPER || testString == BROWSER_TOOLS)) {
                nativeDelegate.apply(target, args);
                return false;
            }
        }
