If i open the app description page (example: Install roonmatrix on Linux | Snap Store) and click on a video which is linked to Youtube, the video doesn’t start to play. Before I click, the preview image of the video is displayed on the page.
If I take a look into the html code, I see a error message in the console: Refused to load https://youtube.com/embed/ygelt9jC3A8?autoplay=1&cc_load_policy=1&modestbranding=1&rel=0 because it does not appear in the frame-src directive of the Content Security Policy.
Maybe a CORS issue?
