No orders displayed in Commission List

With the latest update, the function to get the failed order commission is updated. And it the updated function ‘wc-draft’ post status is added as arg for WP_Query. ‘wc-draft’ though is not registered as a post status (I only found ‘wc-checkout-draft’ post status).

Is this a bug or is it expected that users will add the ‘wc-draft’ status themselves?
