The issue:

If you execute:

/summon minecraft:block_display ~ ~ ~ {block_state:{Name:"minecraft:chest",Properties:{"facing":"west","type":"single"}}}

It will have the correct values in it's data, but it will always display facing south insted of the indicated facing direction.

Same issue with both chest and trapped_chest.

What I expect to happen:

The display block chest should face the indicated facing direction, it works fine with barrels for example.
