In versions prior to 1.13, when a donkey or mule equipped with a chest walked, (whether autonomously or under player control) the chest would wobble. However, with the shift in mob rotation synchronization to align fully with the player in 1.13 (previously it was only partially synced), this characteristic feature seems to have been inadvertently removed.
Steps to Reproduce:
Summon/Spawn a donkey (or mule)
/summon minecraft:donkey ~ ~ ~ {Tame:1b,SaddleItem:{count:1,id:"minecraft:saddle"},ChestedHorse:1b}Mount it
Walk forward, in third-person view
Observed Behavior:
The chests do not wobble.
Expected Behavior:
The chests would wobble side-to-side just as in previous versions.

Notes:
As pointed out by @unknown, and noted in their attached video, this is also a parity issue with bedrock.

In this instance, I propose marking this bug report as related to MC-178639. Additionally, I'd like to mention that the new model has been implemented in other editions of Minecraft, where the wobbling chest on donkeys and mules has been retained. Therefore, the absence of this wobble in Java Edition may be unintentional.
Horses were remodeled in 1.13 to be "simpler", this came along with removing some animations like their mouth opening, so this is probably an intended change.
