Обернуть shaka-player в директиве AngularJS не работает (this.target.addEventListener не является функцией)

Я хочу обернуть shaka-player пример в директива AngularJS.

Пример проигрывателя отлично работает сам по себе и может воспроизводить MPEG-DASH версию Big Buck Bunny размещен на CDN Akamai.

Однако при попытке использовать shaka-player в директиве AngularJS player.load(url) терпит неудачу с this.target.addEventListener is not a function.

Он также сообщает TypeError: Cannot read property 'textTracks' of null. (В зависимости от браузера порядок этих ошибок иногда меняется на обратный)

Я не знаю, почему он работает автономно, но не в директиве AngularJS ...

Фрагмент HTML для директивы выглядит так:

<tq-video-player
  tqsrc="source"
  poster="somePicture"
  id="my-video"
  width="640"
  height="360">
</tq-video-player>

Сам код директивы почти скопирован из кода примера. (Я также пробовал несколько вариантов обработки обещания вместо функции async. У всех одна и та же ошибка.

var TqUiLib = TqUiLib || angular.module('tqUiLib', []);

TqUiLib.directive("tqVideoPlayer", 
function($timeout, $parse)
{ 
    var directive =
    {
        restrict: 'E',
        template: '<video controls width="640"></video>',
        scope: 
        {
            tqsrc:  '=', 
            poster: '=',
            width:  '=', 
            height: '='
        },
    
        link: function(scope, element, attrs)
        {
            console.log("tqVideoPlayer link. nodename", element[0].nodeName, element);
        
            // Install built-in polyfills to patch browser incompatibilities.
            shaka.polyfill.installAll();

            // Check to see if the browser supports the basic APIs Shaka needs.
            if (!shaka.Player.isBrowserSupported())
            {
                // This browser does not have the minimum set of APIs we need.
                console.error('Browser not supported!');
            
                let errDiv = angular.element("<p class='tqVidPlayerErrDiv'>Video player not supported in this browser</p>");
                element.append(errDiv);
            
                throw new Error('Video player not supported in this browser');
            }
    
            let videoTag = angular.element(element).find("video");
            shaka.log.setLevel(shaka.log.DEBUG);
        
            var player = new shaka.Player(videoTag);
            player.addEventListener('error', errorEventHandler);
        
            let srcUrl = "https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps.mpd";
            console.log("Loading...", srcUrl);
        
            loadPlayer(srcUrl);
        
            async function loadPlayer(srcUrl)
            {
                console.log("loadPlayer()");
                try
                {
                    await player.load(srcUrl);
                    console.log("Video is loaded");                 
                }
                catch (e)
                {
                    console.log("player.load failed: ", e);
                }
            };
        
            // Error event handler
            function errorEventHandler(evt)
            {
                console.log("Error Event ", evt.detail);    
            };
        
            // Destructor.  Unbind non-angular listeners
            scope.$on('$destroy', function()
            {
                player.removeEventListener('error');
            });
        }
    };

    return directive;
