Cancel Order Observer not executed when scope is frontend or webapi_rest scope

[bscthartmann]

Preconditions and environment

Magento 2.4.7-p8
PSP: Mollie

When a refund is made or an cancel of the order, this is done via webhook etc. More important it work in the scope "frontend" with Mollie. That means the event "order_cancel_after" to execute "Magento\GiftCardAccount\Observer\SalesOrderCancelAfter" is not handled since the following xml is located within etc/adminhtml/di.xml.

    <event name="order_cancel_after">
        <observer name="magento_giftcardaccount_global"
                  instance="Magento\GiftCardAccount\Observer\SalesOrderCancelAfter" />
    </event>

For me this looks like a bug since this prevents for instance gift cards from being refunded.

Steps to reproduce

1. Make an order with a gift card
2. Cancel the order via Mollie webhook or with a test script and emulation of frontend scope
3. Check if gift card is restored

Expected result

Gift Card is restored with the full value

Actual result

gift card was not restored and gift card history table was not updated
