I tested it on a server without plugins and datapacks.

Folia version

This server is running Folia version 1.21.6-6-ver/1.21.6@e4b0ae9 (2025-06-29T03:17:11Z) (Implementing API version 1.21.6-R0.1-SNAPSHOT)

Other

This bug does not exist on the Paper core, it is a bug of the Folia core. I checked it on the Paper version 1.21.7.

Perhaps if the head flies from one region to another, the same behavior will occur.

Does this issue occur on Folia 1.21.8?

@Dueris I checked it, the bug still exists on Folia 1.21.8.
