Playlist progresses to next video but does not update duration in the metadata in demo

[kiily]

In the demo environment, when you load a playlist, it loads fine, you can play the video, and then if you seek to the very end, the playlist progresses to the next video, but the metadata around the duration is not updating. You can do this with any YT playlist

I'm not sure if that's a bug or whether there's an event listener that's missing, and if so, what event should it be?
