The bug

In Java Edition snapshot 22w17a, the item model for fences was fixed so it more closely resembles how it actually looks when placed in the world (MC-249032). However, this change is yet to carry over to Bedrock Edition.

How to reproduce

In both Java Edition and Bedrock Edition, simply procure a fence item and inspect its geometry.

Expected results

Since Bedrock Edition's model is wrong, it should be updated to match Java Edition's.

Actual results

The old, incorrect item model persists.

Further notes

Instead of changing Bedrock Edition's fence item model to match Java Edition's, it might be worth changing it to the model provided in MC-182716, as well as changing the wall item model to match the wall model currently used in Java Edition, for internal consistency's sake. A fence item does not place down two posts (and nor does a wall), so the item model is misleading in this aspect.
