Active subscriptions not returned by WC_Order_Query

Good morning,

I want to find all subscriptions of a customer using WC_Order_Query. For some reason, when a subscription is set to Active the subscription is not returned by the following query:

            // Get the current users subscriptions
            $query = new WC_Order_Query( array(
                'type' => 'shop_subscription',
                'customer_id' => get_current_user_id(),
                'orderby' => 'date',
                'order' => 'DESC',
            ) );
            $orders = $query->get_orders();	

When I set the subscription to On Hold, the subscription is returned by the query. I don’t apply any filtering in the query, so what causes this issue?

Thanks in advance,

Bèrke
