Netherite Upgrade does not work in worlds where the update_1_20 data pack is ordered before the vanilla data pack

The Bug

Netherite Upgrade cannot be inserted into a smithing table when the "vanilla" data pack overrides the "update_1_20" experimental data pack.

To Reproduce

1. Create a new world.
2. In the Data Packs menu, add the "update_1_20" data pack.
3. Hover over the Default ("vanilla") data pack and click the up arrow.
4. Make sure that the "vanilla" data pack stays on top.
5. Exit the menu and create the new world.
6. Grab a Netherite Upgrade and a smithing table.

Expected Result

You would be able to insert the Netherite Upgrade into the smithing table.

Observed Result

You cannot.
