Minecraft: 1.21.1
NeoForge: 21.1.209
Ars Nouveau: 5.10.4

Reproduce:

• Rename Arcane Pedestal
• Place the Pedestal in the world
• Observe that the Pedestal has the new name (Jade)
  • Storage Lectern correctly adds a new tab
  • Breaking the Pedestal correctly drops renamed item
• Save and quit
• Load back into the world
• Observe that the Pedestal no longer has a custom name (Jade)
  • Storage Lectern no longer has separate tab for the Pedestal
  • Breaking the Pedestal drops normal (not renamed) Arcane Pedestal item

Pedestals and Platforms behave identically.
Chests, Hoppers and Repositories all work as expected.
