Correctly dispose video element

I’m using a video texture in a custom shader. How can I correctly dispose of the video element?
It seems there is no javascript API for this?

Here is my current script

PosteffectNormalVideo.prototype.initialize = function () {
    if (this.videoAsset) {
        this.videoTexture = new pc.Texture(, {
            format: pc.PIXELFORMAT_R8_G8_B8,
            autoMipmap: false,
            flipY: true
        this.videoTexture.minFilter = pc.FILTER_LINEAR;
        this.videoTexture.magFilter = pc.FILTER_LINEAR;
        this.videoTexture.addressU = pc.ADDRESS_CLAMP_TO_EDGE;
        this.videoTexture.addressV = pc.ADDRESS_CLAMP_TO_EDGE;

        let video = document.createElement('video');
        video.addEventListener('canplay', () => {
            this.entity.script["posteffectNormal"].effect.normalMap = this.videoTexture;
        }, { once: true });

        video.src = this.videoAsset.getFileUrl();
        video.loop = true;
        video.muted = true;;

        this.on('destroy', () => {
            video.src = '';

After destroying I can still see the Media in Chrome Dev Tools

Altough I suspect this happens because Chrome Dev Tools never clears this list (even stays visible after navigating).
What bugs me is that there is no kWebMediaPlayerDestroyed event called. Which I did see once.
