Currently the above mentioned function is dropping all args - even WooCommerce internal args for e.g. variants.
Therefore the customer cannot reorder the exact same product without re-configuring it. This is a bummer because we want to make it easy for our customers to reorder what they already liked.
Please make sure that add_edit_link_to_order_item() in class-order.php is not dropping the URL args others have already inserted. There might also be other plugins which would malfunction due to this issue.
Added in 3.3.2
