No fall damage.

What I expected to happen was...:
Dropping from y=200 should cause death regardless of enchants as it does in 1.14.60.

What actually happened was...:
With just leather boots with feather falling 4 and protection 4 only 5 hearts of damage is taken, none with an additional protection 4 item.

Steps to Reproduce:

1. Equip any boots with feather falling and jump from y=200
2. Notice you are no longer living
3. Apply protection 4 to the boots (in addition to feather falling) and jump again
4. Note barely any damage is taken and health is regained extremely quickly

Notes:

• Works with any type of boots (leather through netherite)
• MCPE-74826 posits that protection is somehow amplifying the feather falling in 1.16
• Doesn't appear to work with any other form of protection (ie projectile)
