Я пытаюсь использовать тот же код, который используется в этом ответе , но вместо этого я получаю сообщение об ошибке в журнале консоли:

Код 

<svg version="1.1" class="center-block" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="800" height="600"  style="border: 1px solid black;">
    <g>
        <g transform="translate(151,104) scale(1,1)">
            <rect x="0" y="0" width="300" height="200"></rect>
            <foreignObject x="-151" y="-104" width="500" height="400">
                <video width="300" height="200" controls="" style="position: fixed; left: 151px; top: 104px;">
                    <source src="http://techslides.com/demos/sample-videos/small.mp4" type="video/mp4">
                </video>
            </foreignObject>
        </g>
    </g>
</svg>

Если я скопирую код и вставлю его, используя инструменты разработчика (F12), все работает, и видео играет хорошо. мне нужно что-то добавить в код или в мое приложение, чтобы Angular мог хорошо построить элемент?

это моя angular версия:
