The Bug:

The rotation of controlling passengers on sitting camels is sometimes restricted while adjusting your rotation slowly.

At certain times the player is unable to spin a full 360 degree circle on a camel while in other cases it is able. This does not seem to be affected by the angle of the player's head but rather the speed of the player's body movement

Steps to Reproduce:

1. Summon a camel with a saddle already equipped on it by using the command provided below.

   /summon minecraft:camel ~ ~ ~ {SaddleItem:{id:"minecraft:saddle",Count:1b}}

2. Wait for the camel to sit and when it does, mount it.
3. While moving your mouse slowly, attempt to adjust your rotation a full 360°.
4. Take note of how just before you're facing 180° away from the camel, you are restricted to adjust your rotation any further.
5. While moving your mouse faster this time, attempt to adjust your rotation a full 360°.
6. Take note of how you're able to do so.

Observed Behavior:

The rotation of controlling passengers is sometimes restricted.

Expected Behavior:

The rotation of controlling passengers would not be restricted at all.
