Get Playlist Items endpoint does not return artist images

[TheKingElessar]

The Get Playlist Items endpoint specifies that, for each artists array for each track item, an array of artist images are returned. For example:

{
	"items": [{
		"track": {
			"artists": [{
				"images": [{
					"url": "https://i.scdn.co/image/ab67616d00001e02ff9ca10b55ce82ae553c8228",
					"height": 300,
					"width": 300
				}]
			}]
		}
	}]
}

However, the endpoint currently does not return the proper images array. This is the entire artists object:

{
	"items": [{
		"track": {
			"artists": [{
				"external_urls": {
					"spotify": "https://open.spotify.com/artist/6zFYqv1mOsgBRQbae3JJ9e"
				},
				"href": "https://api.spotify.com/v1/artists/6zFYqv1mOsgBRQbae3JJ9e",
				"id": "6zFYqv1mOsgBRQbae3JJ9e",
				"name": "Billy Joel",
				"type": "artist",
				"uri": "spotify:artist:6zFYqv1mOsgBRQbae3JJ9e"
			}]
		}
	}]
}

And you can see that it's missing the images array. This can be easily tested using the "Try it" tool at the documentation linked above. No matter the playlist, the images array is missing.

I have to assume this is an issue on the back-end, because it's pretty clear I'm not doing anything wrong (you can try it yourself with the documentation's "Try it" tool).

Does anybody know what's up with this?
