26
	 * This implementation of get_objects_by_id() is a bit hacky since we're not passing in an array of meta IDs,
27

28
	 * we also pass in an associative array where we expect there to be 'meta_key' and 'ids' keys present.
29
	 *
30
	 * This seemed to be required since if we have missing meta on WP.com and need to fetch it, we don't know what
31
	 * the meta key is, but we do know that we have missing meta for a given post or comment.
32

33
