Can't use Processing crafts into storage drawer.

When dispatching a processing craft into a Drawer from Storage Drawers, just the first item is inserted into the drawer.

This is useful to create processes that require an order for items to be sent (which can be resolved with PR #3014), but I still need to insert one by one, the only way I found for now is to use a storage drawer, or any other storage that allows a single type of item at a time, once the first item is pulled from the drawer, the next ones are not being inserted as expected, this breaks the whole process.

Steps to reproduce:

1. Set a processing recipe of at least 2 different items for input.
2. Put the pattern in a crafter facing a drawer from Storage Drawers, for testing only, you could just automatically pull the items from the Drawer right after the insertion, putting a dropper below should do it.
3. Request the item from the system.
4. The first item will be inserted normally into the Drawer and pulled right after, leaving the Drawer free to insert other items, but the next ones won't.

Version:

• Minecraft: 1.16
• Forge: 36.2.4
• Refined Storage: 1.9.15
• Storage Drawers: 8.3.0
• All The Mods 6 (modpack): 1.8.4

Inserting different items into the Drawer this way is working fine with other Mods that push items some way (Mekanism, Pipez, etc), so I assume the problem is only with Refined Storage and not with the Storage Drawers mod

Unlike pipe mods RS will insert the 2 items at the same time instead of one after another. This works once due to the rather questionable way Storage drawers stores its items.

Use a buffer if you really need the items to go into drawers for whatever reason.
