Fire tends to prevent fall damage

The bug

While on fire, the player is often immune to fall damage. From my testing, this does not seem to affect other kinds of damage-over-time effects like poison, or other types of damage like enemy attacks.

How to reproduce

1. Get on a high pillar and place fire
2. Enter survival mode, get lit on fire, then jump off
3. Land
It's not perfectly consistent, but is relatively easy to recreate
