Expected Behavior

Cake does not get eaten when picked up.
or
Cake reduces NBT value to show another slice was taken when picked up.

Actual Behavior

Slice of cake gets eaten when picked up, but a slice does not get removed from cake in hand.

Steps to Reproduce

(Pick up all blocks must be enabled)
1: Place a cake.
2: While hunger bar is not at full, use CarryOn to pick up the cake.
3: Observe hunger bar being restored 1 cake slice.
3: Place the carried cake down again.
4: Observe the cake is still the same as before picked up.

Screenshots encouraged

Also, you can see that there is a texture issue with the picked up cake. I figure there doesn't need to be a second issue opened for this as this is likely expected to happen with various non-entity blocks that behave like cake does.
