FPS drop with alex's head - Minecraft 1.16.5 vanilla

https://youtu.be/FzM_XnPhp84

happens when it loads the chunk where the head is located. If it gets too much the game can crash the whole computer. The same thing happens on public servers.

I made a video because I don't speak English very well; and also because with a team of millions and millions of dollars they should be able to solve this kind of bugs that have been going on for years!

It also happens with the latest snapshot of Minecraft: XXX.
In 1.15.2 I was also able to reproduce the bug, in fact when you place a head on the ground the game crashes. I searched for this crash and it turns out that someone had already reported it, the Mojang bug team (moderators) dismissed the report.
