Loot Table Function does not work on Geyser on a 1.20.4 server
The Loot Table Function does not work properly with Bedrock clients using Geyser. Upon opening the chest, instead of showing a double chest UI with items, it shows an empty single chest UI.
Everything works fine on Paper 1.20.2, MythicDungeons 1.4.0, ViaVersion 4.10.2, ProtocolLib 5.1.1-b669. Only the server version was changed from 1.20.2 to 1.20.4 and ProtocolLib updated from 5.1.1-b669 to 5.2.0-b679 for this bug to happen. Perhaps it's a Geyser bug, but to report it to Geyser, they probably need some relevant internal info on how MD opens virtual inventories, so I am submitting this bug report here first.
