Screencast showing visual artifacts on web.whatsapp.com

In WhatsApp Web, when zooming in and out of an image using the website's media viewer, visual artifacts are left on the screen as shown in the screencast attached.

2. Visit web.whatsapp.com
3. Send/ receive a photo
4. Inspect the photo by clicking on it
5. Click on the photo again to zoom in
