Holding Wolf Armor in the off-hand causes the wolf to incorrectly equip the main-hand item.

In Bedrock Edition 26.70.24 beta/Preview, Mojang made some adjustments to the off-hand. By using commands, any item can be placed in the off-hand, and some items can be used from the off-hand. However, after this adjustment, tamed wolves will incorrectly equip and display the armor and Happy Ghast harness in the player's main hand.

Reproduction steps:

1. Use the following command to give yourself Wolf Armor in your off-hand:

/replaceitem entity @s slot.weapon.offhand 0 wolf_armor 1

2. Tame a wolf using bones.

3. Hold any of the following items in your main hand: a helmet, chestplate,elytra,leggings, boots, or harness.

4. Right-click a tamed wolf while holding any of the above items in your main hand.

Expected result:

The tamed wolf should equip the Wolf Armor in the off-hand, not the item in the main hand.

Actual result:

The tamed wolf incorrectly equips the item in the main hand. If the main-hand item is a wearable item, it will incorrectly appear on the tamed wolf's model.

Additional information:

Not all wearable items will appear on the wolf in this way. For example, saddles, horse armor, and nautilus armor will not appear on the wolf's model.
