ambient_occlusion_exponent field in blocks.json does not affect certain Block Entities

Relates to MCPE-187536 and MCPE-190242.

The new ambient_occlusion_exponent field in blocks.json has no effect on the following blocks:

• Chest (all)

• Heads and skulls (all)

• Decorated pot

• Conduit

• Banner (all)

• Sign (all)

• Hanging sign (all)

• Shulker box (all)

• Cauldron

• Bed (all)

• Repeater

The attached sample pack sets the ambient_occlusion_exponent of all the blocks in the list above to 100. It also sets this value for "grass_block" to prove the pack is working.

Despite setting this value on all the blocks from the list above, these blocks appear unchanged in-game:

4. Observe that this new block is not darkened, despite having the same configuration in blocks.json as the grass block.

Expected Result

ambient_occlusion_exponent works on any block.

Observed Result

ambient_occlusion_exponent does not work on certain block entities.
