Items are invisible on falling campfires with TileEntityData

If you create a falling_block entity for minecraft:campfire or minecraft:soul_campfire with items specified, those items cannot be seen on the campfire entity, even though they show up just fine in the block form.

To reproduce:

/summon minecraft:falling_block ^ ^2 ^5 {BlockState:{Name:"minecraft:campfire"},Time:1,TileEntityData:{Items:[{count:1,Slot:0b,id:"minecraft:cod"}],CookingTotalTimes:[I;9999,0,0,0],CookingTimes:[I;0,0,0,0]}}

Expected results: as the campfire falls you should see the items on top.

Actual results: the items are completely invisible until the moment the campfire touches the ground.
