On latest tests-passed branch, topics with a bare YouTube playlist URL are OneBoxing correctly, but no thumbnail is produced. An example:
https://www.youtube.com/playlist?list=PLJtitKU0CAeiFIQUX81qqt4laVWfa-Gtz
A related question, is it possible to rebake only posts that have no thumbail? i.e. a version of rake posts:rebake that includes a query?
Thanks @D8vid, I’ll take a look
For normal YouTube videos, we use a custom embedding system. This doesn’t support the playlist UI. So that explains the difference.

We’re not planning any immediate changes here, but I’ll leave this topic open as a feature request.
A few years have passed, is there any community interest in one boxing YouTube Playlist urls?
