Cart items created through uc_reorder to not match the new Ubercart attribute cart data format

Although the product attributes still display when using the old attribute format, the attribute data array created for cart items by uc_reorder no longer matches the upstream format. Below are some snippets of print_r($item->data['attributes']) during cart view that demonstrate the change in format.

Normal, item added to cart through product form:

Array
    (
        [1] => 2
        [2] => 6
        [3] => Array
            (
                [7] => 7
                [8] => 8
                [9] => 0
            )
  
    )

Reordered item, before patch:

Array
    (
        [1] => Array
            (
                [0] => 2
            )

        [2] => Array
            (
                [0] => 6
            )

        [3] => Array
            (
                [0] => 7
                [1] => 8
            )

    )

Reordered item, after patch:

Array
    (
        [1] => 2
        [2] => 6
        [3] => Array
            (
                [0] => 7
                [1] => 8
            )

    )

AID 1 and 2 are drop-down menus, AID 3 is a series of checkboxes (same format as radio buttons).
