Issue Description

If you have the inventory of a conveyor belt layer open, then place conveyor belts using the conveyor belt layer, the conveyor belts inside the conveyor belt layer and their count turn invisible until you manually refresh the inventory of the conveyor belt layer.

What did you expect to happen?

For the count of the conveyor belts to update properly, and the items to not turn invisible.

What happened instead?

Invisible conveyor belts inside the inventory of the conveyor belt layer.

Why is this bad/What are the consequences?

Broken ui is bad.

Steps to reproduce the issue.

1. Get a conveyor belt layer.
2. Fill it with conveyor belts.
3. Open its inventory by alt clicking it.
4. Place a conveyor belt.
5. Notice the conveyor belt inside turn invisible.

Extra information

This bug seems related to several other inventory count bugs such as #18714 this was "fixed" by adding slight tedium by not allowing items inside to be changed into other items (cutting logs into planks in the mentioned issue). However this doesn't seem possible here, unless the conveyor belt layer looses its inventory and instead uses a count that goes up and down.

Side note, its kind of odd that an item with 7 slots can only hold 7 or so conveyor belts.
