Got some strange behavior with matrix items and out of stock behavior. If I have a matrix item parent with the out of stock behavior set to "Remove item when out of stock" and any of the children have zero stock, then the whole item (all matrix variants) are pulled from the site. Is that how it's supposed to work?

That's not expected at all indeed.

I'm disabling some extensions to see if somehow I caused it. The item disappears from search result calls as well which has me puzzled.
