For some reason my out-of-stock products reappear as 'in stock' whenever I update the product by a csv import.

Even if I import a single column; the 'sku' column, the affected products suddenly appear in stock.

I don't want imports to affect the stock level, as I'm constantly updating products via csv on a live store. I have intentionally left out all qty or stock related columns on my import sheets.

Does anyone know why this is happening? Is it an intended feature, a bug, or configurable? Stock management is enabled in config, and all products use config settings for stock management. I'm using Magento 2.1.7

So Backorders were enabled in my Magento admin inventory config, and this seems to ALWAYS set my products 'In stock' after a csv update. Disabling backorders stopped this behaviour.

However, note that products are still automatically set as 'In stock' if quantity is higher than the out-of-stock treshold, even if stock is not changed by the import. I guess it's the stock re-indexing that causes this.
