CREATED Order - Stock and more...

-- HikaShop version -- : 4.7.1
-- Joomla version -- : 4.3.2
-- PHP version -- : 7.4

Dear support,
I have more questions about the "Created" status of an order.

1) I understand that a created order should reduce the stock number to avoid overbooking, but I did a test adding a product to the cart and when in the external payment gateway I just closed the window. In this case, the order status remained Created since I did not want to cancel it for this test purpose. Unfortunately, the stock remained the same.
Shouldn't it be reduced and restored in case of cancelled order?

2) Concerning my test, is there a moment when the dead "Created" order will expire and be automatically cancelled?

Kindest regards
Lorenzo
