The issue was reported via webcomopat.com reporting tool. We have moved the issue as picture-in-picture is a browser feature. Please feel free to move the issue to the relevant Product/Component.

Arte appears to be using its own video player (avp). We can create a new site-specific wrapper to detect and render captions on the PiP window.

Note: you may need VPN to access the link. I used a Belgium server.
