[Plugin: Jetpack] Publicized posts missing embeds

Publicized posts are always missing the embeds when posting to any site. It creates the worst kind of repost to another site that isn’t useful for anyone. I’m not sure if this is a misconfiguration on my part, or just the default behavior of publicize. Here’s an example.

I post via marsedit and use the [embed] function.
