YouTube controls in background video

Hey all,

Recently spotted something that wasn’t there before (as far as I know). I have several websites that have a hero section with a YouTube video (link) as a background. Works perfectly fine, but I recently found out that you see the controls for about 5 seconds. Can’t click it because it’s a background and it fades away after a couple of seconds.

As far as I know, this wasn’t there when I built it. Does anyone know if anything changed? Is there a new setting I missed? Is it a bug or a YouTube thing?

More important: how do I get rid of it? Haha. If anyone knows, thanks a bunch!
