Inconsistent is_on_ground predicate with attributes bounciness 1 and air_drag_modifier 0

Summary

When the player has a bounciness attribute of exactly 1, and an air_drag_modifier attribute of exactly 0, using a predicate to test is_on_ground is inconsistent, even within a single tick.

When in the air, the predicate always returns false, as expected. When on ground, the predicate mostly returns true, but sometimes returns false.

Note that I am not jumping or dropping of a ledge before running the predicate. This happens when standing perfectly still, even after holding the crouch key to prevent bouncing.

Steps to reproduce:

1. Create a new world in creative mode with cheats

2. Stand on the ground

3. Run the following 2 commands:

   1. /attribute @s minecraft:bounciness base set 1

   2. /attribute @s minecraft:air_drag_modifier base set 0

4. Run the following command multiple times to observe the result:

   1. /execute if predicate {condition:"minecraft:entity_properties",entity:"this",predicate:{flags:{is_on_ground:true}}}

5. Note that the result is sometimes true, and sometimes false. You can even observe different results within a single tick, like when using /tick freeze

Expected behavior:

Using this exact combinations of attributes should not cause different behavior; the predicate should always return true when the player is standing on the ground.
