[MC-276755] Teleporting an entity makes the "is_on_ground" flag in predicates always return true for that tick

Steps to reproduce :
-Place a repeating command block with the following command :

execute as @p at @s if predicate {"condition": "minecraft:entity_properties","entity": "this","predicate": {"flags": {"is_on_ground": true}}} run say On Ground

-Spam the following command in chat a few times while flying in either creative or spectator mode :

tp @s ~ ~ ~

Observed Behavior :
The "is_on_ground" flag sometimes returns true depending on when in the tick, you run the tp command in chat.

Expected Behavior :
The predicate won't return true if the player wasn't on ground before and after getting teleported

_{For those trying to find a workaround for this,}stepping_onair_{actually works, so all you have to do is invert or}unless_it. Turns out it has it's own issues
