Picture in picture is blank when loaded from the sidebar

[dmac-au]

What happened?

I have just downloaded Zen today and I love the Sidebar as it's something I use in Vivaldi as well.

My problem is when I load YouTube in the sidebar, I want to be able to open the video in a Picture in picture window so I can close the sidebar or keep the pip window if I switch desktops, etc.

The "Pop out this video" button is visible, but when I click it, the pip window is blank and the video is still playing inside the sidebar.

The grey box in the screenshot has all of the normal PiP decorations (play/volume/etc) but you can't close it and it obviously isn't playing the video. Even pressing the close icon doesn't work and I have to ALT+F4 the window.

I tried Disable Mobile UserAgent and same thing.

I am running 1.0.0-a.20 (64-bit) Linux Specific on Fedora 40 and KDE Plasma 6.1.

Happy to provide any other information if you need.
