[MC-183356] The base of two armor stands Z-Fight

Z-fighting can be seen when the bases of two armor stands intersect one another.

Summon two armor stands relatively close to one another so that their bases collide.
```
/summon minecraft:armor_stand ~2 ~ ~
/summon minecraft:armor_stand ~2 ~ ~0.5
```
Look at where the bases of the armor stand intersect one another.
