 I'm not sure if this is expected or not, but I'll report it because it
 seems unexpected to me.

 Maybe this is also not really the problem of the REST API, but it affects
 it regardless.

 If the post has a thumbnail ID that is invalid (e.g. the post was imported
 with invalid IDs), it is still returned by the API. If linked resources
 are embedded there will be a 404 error inside the response.

 Of course when someone uses the api, they should check for errors in the
 embeds, but it would be nice if linked resources don't 404.

 `has_post_thumbnail` doesn't seem to check this either...
