Picture in picture no longer working for Youtube

Previously, picture in picture worked as intended, with hitting the home button playing my videos no problem. Now, at least on YouTube, it displays the box where the video should be playing but instead of playing, it just shows the top of the web page. The video does not play, it remains paused no matter what you do. It doesn't seem to affect every website, as I tested it with the iMDB video player and that worked without a hitch. It makes YouTube unusable in picture in picture. This started a few days ago, and no matter what I try, I have been unable to resolve it. I've included an image of what the issue looks like over a game, but it looks like that no matter which app you're in.
