The horse from 1.19.4 to the most recent version 1.20.1, does not run

Hello how about mojang developers, I want to show that from version 1.19.4 to 1.20.1. The horse no longer runs like in version 1.19.3.
Idk if it is some implementation of these versions or is it a bug. Hope it helps, thanks.

Postscript: I leave some videos as evidence, one corresponds to version 1.19.3 and the other to version 1.20.1
