When trying to summon an armorstand with the noGravity tag, it still falls to the ground as normal when having the render distance at value 32. Additionaly the tag doesnt show up when using /data get [armor_stand] at all.

To reproduce, just try to use this command:
summon minecraft:armor_stand ~ ~ ~

(the Lagg in my Video is not visible in my game. It just occurs when recording, so it isnt the reason)
