Is it intentional that the Extractor Attachment does not round-robin check inventories it is extracting from? For example, if I am extracting from a chest to a furnace, if the very first item in the chest is NOT cookable, then the extractor will pause indefinitely and not check any other items in the chest, even if the rest of them can be cooked. Basically, if the extractor comes across an item that is incompatible with the target inventory, then it will pause at that item, even if there are other items in the chest that fit the criteria. Tested with all levels of pipes and extractors. Is this a bug?

Update: The issue doesn't seem to happen when you place the item blocking the extraction on a blacklist, presumably because it skips it. Still seems like a bug this behavior happens even on a no blacklist extractor.
