Youtube thumbnail fails to show up on Topic List for e.g. Fakebook theme, TLP plugin.

STR:

Post a youtube video, switch to Fakebook Theme, no thumbnail appears.

Workaround:

Rebuild the post and the thumbnail appears, however, given users are expecting the thumbnail to appear imminently without staff intervention, this is not a great solution.

More info:

`Topic.image_url` appears to be `nil`

This seems to have broken recently, after beginning of August … I think this worked before August the 5th (but not sure when it actually broke). I’ve noticed this aligns roughly with a new version of Onebox …

I tested this on a prior build and the issue was not present, ruling out Youtube og responses I hope. Also Fakebook theme shows the same behaviour as TLP plugin, ruling out TLP plugin, so I do suspect it’s a recent regression in Discourse or Onebox.

This is a real issue for users of Topic List Previews.
