SplitOrder not persisting shippingLines in SellerOrder

[buisine]

Describe the bug
SplitOrder strategy works well on execution, but the shippingLines data is not persisted.

To Reproduce
Steps to reproduce the behavior:
easier way : Make a multi seller order, and then look at the aggregateOrder and the sellerOrder.

Expected behavior
To have shipping lines persisted and then returned by Api in SellerOrder, ( admin, emails )

Environment (please complete the following information):

• @vendure/core version: 2.1.6
• Nodejs version 20.9.0
• Database (mysql/postgres etc): MariaDB 22.04

Additional context
Some hydration not happening somewhere ?
some logs from splitOrderStrategy execution :

This is showing a shipping line in the splitOrder function return.

[server] splitOrder ~ [...partialOrders.values()][0].shippingLines: [
[server]   ShippingLine {
[server]     createdAt: 2024-05-14T09:42:52.572Z,
[server]     updatedAt: 2024-05-14T09:42:52.000Z,
[server]     listPriceIncludesTax: false,
[server]     adjustments: [],
[server]     taxLines: [ [Object] ],
[server]     id: 172,
[server]     shippingMethodId: 45,
[server]     listPrice: 200,
[server]     price: [Getter],
[server]     priceWithTax: [Getter],
[server]     discountedPrice: [Getter],
[server]     discountedPriceWithTax: [Getter],
[server]     taxRate: [Getter],
[server]     discounts: [Getter]
[server]   }
[server] ]

Full Array returned by SplitOrder looklike this :

[server] splitOrder ~ [...partialOrders.values()]: [
[server]   {
[server]     channelId: 33,
[server]     shippingLines: [ [ShippingLine] ],
[server]     lines: [ [OrderLine] ],
[server]     state: 'ArrangingPayment'
[server]   },
[server]   {
[server]     channelId: 5,
[server]     shippingLines: [ [ShippingLine] ],
[server]     lines: [ [OrderLine] ],
[server]     state: 'ArrangingPayment'
[server]   }
[server] ]

in order.service ?
missing some lines relation ?

    getSellerOrders(ctx: RequestContext, order: Order): Promise<Order[]> {
        return this.connection.getRepository(ctx, Order).find({
            where: {
                aggregateOrderId: order.id,
            },
            relations: ['channels'],
        });
    }
