Fall Damage Multiplier makes low falls safe, overriding Safe Fall Distance

The safe_fall_distance attribute is supposed to decide the distance the player can fall before they start receiving fall damage, while fall_damage_multiplier should only decide how much is taken; but when fall_damage_multiplier is less than 1, it prevents damage at heights where the damage would be less than 1.

Here’s an easy way to reproduce:

1. Set Safe Fall Distance to 0 with attribute @s minecraft:safe_fall_distance base set 0

2. Jump or fall 1 block, dealing a half heart of damage. Works as expected.

3. Set Fall Damage Multiplier to 0.5 with attribute @s minecraft:fall_damage_multiplier base set 0.5

4. Jump or fall 1 block again. Instead of taking half a damage, it’s negated entirely.

Expected Result: Player takes partial damage, the same way Feather Falling works.

Produced Result: No damage is taken at all?

Main reason this is a problem is that one of the datapacks I use makes players smaller, so falling 2 blocks inflicts damage. I thought trying to make the damage more bearable by decreasing it would work, but it just effectively undoes the change to their safe fall distance.
