Shulker Box and bundle item entities don't account for count when dropping contents
If a stack of bundles or shulkers is dropped as an item and destroyed it will only drop for one.
To Reproduce:
- /give @s bundle[minecraft:max_stack_size=2]
- place atleast one item in the bundle
- copy with middle mouse click
- drop whole stack onto the ground
- /summon tnt
- pick up remaining items and notice there is only the quantity of a single bundle, not multiple
