I'm not a developer, so maybe I misunderstand what PiP is strictly speaking. But, I thought I had been using PiP for a couple of years now in Firefox. https://support.mozilla.org/en-US/kb/about-picture-picture-f...

Is this not PiP?

According to caniuse, it's a proprietary implementation that's only partially implemented [1].
