16673	_wp_translate_data() shouldn't set fields to empty values	scribu	scribu	"In _wp_translate_data(), there are 3 fields which are always set, regardless if their $_POST key wasn't set originally.

This prevents the [https://core.trac.wordpress.org/browser/trunk/wp-includes/post.php#L2667 array_merge() in wp_update_post()] from working properly.

Example: If a custom post type doesn't support excerpts, they will be overwritten if you set them through another method.

In #13179, this was resolved by adding hidden inputs, which is kind of backwards.
