Thanks, I already have a very solid idea why it happens for me: Because I have `Referrer-Policy: same-origin` set. This means no `Referer` for embedded Youtube, breaking the embed. A similar effect could occur with strict tracking protection settings in browsers.

That’s fine though. I mean, I would certainly prefer it if the Youtube Onebox would use `youtube-nocookie.com`, which may or may not help, but that’s a different topic.

Instead, I want to understand and fix Lazy Videos. It’s superior anyway. But I have no idea what to try.
