AngularJS 1.5 Decorator not working for $log

Question

I've decorated the AngularJS $log service, but I can only see it load the config and none of the $log methods are decorated. This used to work and I have a lot of $log.info(...); in the application that I need to be turned off for a deploy, but even with production being set they continue to be logged to console. I abridged the methods decorated down to just info for brevity.

Can anyone see what has happened or is wrong? This is pretty textbook and when I noticed it wasn't working anymore I checked a bunch of sources and they appear to be doing it the same way.

(function () {

    'use strict';

    /**
     * Registers a decorator for the $log service.
     * @param {Object} $provide
     */
    function logConfig($provide) {

        console.log('CAN SEE CONFIG BOOTSTRAP');

        $provide.decorator('$log', extendLogHandler);
    }

    logConfig.$inject = [
        '$provide'
    ];

    /**
     * Turns off logging to the console based on the environment set in the configuration
     * settings as long as logging was performed through AngularJS' $log component.
     * @param {Object} $delegate Service instance of $log to be decorated
     * @param {Object} APP_CONFIG
     * @returns {Object}
     */
    function extendLogHandler($delegate,
                              APP_CONFIG) {

        // Saving the original behaviour
        var _info = $delegate.info;

        // Supplant existing behaviour by stipulating the application must be
        // in development mode in order to log
        $delegate.info = function (msg, data) {

            console.log('NOT INVOKED');

            // Prevent all logging unless in development
            if (APP_CONFIG.ENV !== 'production') {

                // Replace the original behavior
                if (angular.isDefined(data)) {
                    _info(msg, data);
                }
                else {
                    _info(msg);
                }
            }
        };

        // Provide the supplanted $log delegate
        return $delegate;
    }

    extendLogHandler.$inject = [
        '$delegate',
        'APP_CONFIG'
    ];

    angular
        .module('app')
        .config(logConfig);
})();

UPDATE

Seems the issue is related to this other config that scrolls the application to the top when ngTable events occur:

function table(UtilsFactoryProvider,
               ngTableEventsChannelProvider) {

    // Reference to new page generation event listener
    var newPageGenerationListener = null;

    var ngTableEventsChannel = ngTableEventsChannelProvider.$get();
    var UtilsFactory = UtilsFactoryProvider.$get();

    // Subscribe to new instances of NgTableParams
    ngTableEventsChannel
        .onAfterCreated(function () {

            // Set the previous page default for new instance
            var prevPage = null;

            // Deregister the any existing page generation event listener
            if (typeof newPageGenerationListener === 'function') {

                // Release memory to prevent leaks
                newPageGenerationListener();
            }

            // Subscribe to new page generation event listener
            newPageGenerationListener = ngTableEventsChannel
                .onPagesChanged(function (events) {

                    // Set the next page
                    var nextPage = events.page();

                    // Only scroll to the top if not a new instance
                    if (prevPage !== null) {

                        UtilsFactory
                            .scrollTop(true);
                    }

                    prevPage = nextPage;
                });
        });
}

table.$inject = [
    'UtilsFactoryProvider',
    'ngTableEventsChannelProvider'
];
