• Trinkets version: 3.3.1
• Minecraft: 1.18.2
• Loader: 0.14.6

I've implemented a chest/back item into my mod following the wiki's Getting Started page and in creative mode I've found a synchronization issue.

Steps to reproduce:

• Place item into trinket slot
• Specifically shift-click the item from the slot into your inventory
  • State change will not be synced to clients, other players will not visually register that the trinket has been removed
• Log out
• Log back in
• Item will have re-appeared in the slot, and the item in your inventory remains

This only happens in creative mode. The duplication isn't a big deal in creative but I believe it's related to the desync. I checked the commits leading up to 3.4.0 on 1.19 and I didn't see anything that would have fixed it, but I'd be happy to try again after updating my mod to 1.19 after BlanketCon.

Edit: I tested this both in a development environment for my mod and in a launcher, it still happens with just my mod and its dependencies:

• Galaxies: Parzi's Star Wars Mod (mine)
• CCA 4.1.4
• Cloth Config 6.2.62
• ModMenu 3.2.2
• REI 8.2.470
• LibZoomer 0.4.2+1.18.2
• GravityChanger API 0.7.7+fabric

If you'd like me to test it in an even more bare environment just let me know.
