For status “in backorder” quantity in bundle is not considered

Hi,
We had to notice that for smart bundles the stock status “in Backorder” is not used the quantity and stock of single products.

To illustrate:

We have a smart bundle of one single product with fixed quantity of 2. For the single product, the inventory is managed at product level. In our scenario, there is only 1 item left in stock. For single product backorder is allowed with notification.

As long as the single product is in stock with 1 item, the bundled product will not change to “in backorder” even though the stock for the bundle is shown in backend correctly with 0, because we need for bundle a stock of 2 items.

When the single product changes to stock 0 and thus to stock status “in backorder”, the bundle will be also set directly to “in backorder”.

Thanks for your help
