No matter what value 'maxEntityCramming' is set to, stacking armor stands or minecarts in a one-block space doesn't have a limit. This can cause extreme lag, even in singleplayer.

What I expected to happen was...:

After the stacked (in one-block space) armor stands/minecarts reach the limit provided by 'maxEntityCramming' gamerule, some of the armor stands/minecarts start to break just like mobs affected by this gamerule die after reaching the limit.

What actually happened was...:

I can infinitely stack armor stands and minecarts in a one-block space without them breaking even if the gamerule is set to 1.

Steps to Reproduce:

(optional) Set the gamerule maxEntityCramming to something small like 3

1. Build a 3 block tall "tower" by placing the block of your choice like in the video down below
2. Place armor stands next to the top block like done in the video down below
3. Notice how you can stack 100, 300, 1000, ∞ armor stands (and minecarts too if done with rails) without a single one breaking (or at least disappearing or doing something)!

I hope this gets fixed, because it can cause a lot of lag and performance issues, and even crash servers.

This is NOT a feature request or a suggestion. If this is how 'maxEntityCramming' works, then this is 'Works As Intended'.

Edit: Now I noticed that it actually duplicates MC-217927. At first I searched, but did not find anything else. Sorry for the duplicate.
