Enchantments from items held in the main hand are applied to other items when entities are killed

The Bug:

Steps to Reproduce:

   /item replace entity @s weapon.offhand with minecraft:bow

   /item replace entity @s weapon.mainhand with minecraft:diamond_sword[enchantments={levels:{"minecraft:looting":100}}]

2. Shoot and kill the husk using the bow.
3. Look if the looting enchantment on the sword affected the number of items that the husk dropped.
4. Take note as to whether or not enchantments from items held in the main hand are applied to other items when entities are killed.
