I have a fairly low-end PC so it would be difficult for me to record my screen, but I can share some steps to recreate: 1. Isolate a naturally spawning endermen that has picked up a block with a minecart or boat 2. move away at least 128 blocks 3. The endermen will remain there, and will no longer count towards the mob cap, allowing more endermen to spawn.
This is only prominent in warped forest biomes as they spawn frequently and there is an abundance of blocks they can pick up and does not occur elsewhere.
