When there are some lag spikes, for example when the world is auto saving, it creates too much lag that it stops players from taken fall damage for a bit of time if they are about to fall from something

Steps to reproduce:
1. Be in a world with more than 5 friends (with decent lag)
2. try falling over and over on the ground
3. you will notice sometimes you won't get any fall damage

Observed Results:
You and many more players don't get fall damage because of lag (not even delayed fall damage)

Expected Results:
We should get atleast delayed fall damage (like in console edition) when we are lagging and fall off a great height
