Magento 2.1.9 updated to 2.2.1 - The problem did not occur in 2.1.9, but it is present in 2.2.1

Products that were out of stock in 2.1.9 had the red slash and your couldn't select that option. After the upgrade, all existing combinations are able to be selected despite being out of stock.

In cataloginventory_stock_status, the items are showing stock_status 0 for items sold in 2.1.9 and 2.2.1
In cataloginventory_stock_status_idx the items are showing stock_status 1 for items sold after upgrading to 2.2.1, and stock status as 0 for items sold in 2.1.9

Not only Swatch.
I'm facing the same issue for simple item and configurable items.
Worst of all, some configurable items is not show even the stock quantity is positive, in stock, and enabled.

Is this not a dupe of #12317?

[mysil2]

@chedaroo Seems to me.

Fixed in 2.2.4-preview branch: #12936

From the latest comment a backport to 2.3 is planned.
