The bug
Stationary entities do not render behind semi-transparent entities, such as spectator players, invisible entities in spectator mode, or friendly invisible team members.
Apparently it only happens to mobs summoned with no AI, the issue is not reproduceable with moving mobs. It also affects chests or any other block, that are block entities.
To reproduce
Summon an invisible armor stand
/summon minecraft:armor_stand ~ ~ ~ {Invisible:1b}
Place a normal armor stand behind it
Switch into spectator mode
Look at the visible armor stand through the invisible armor stand
→ ❌ The visible armor stand does not render behind the invisible onePress F5
Look at the visible armor stand through yourself
→ ❌ The visible armor stand disappears behind you
If graphics settings is set to "Fabulous", the issue no longer persist.
