Enchantment attribute doesnt get applied when switching away from offhand.

What happens?:

When you have a enchanted Item equipped in off-hand and switch it with the main hand by pressing 'F'. The attribute that was applied through the enchantment will be removed even though the player still has the item in an active slot.
