Using the look command with yaw and/or pitch args while riding an entity does nothing.
While not riding an entity, using the offthread_repeat argument with yaw and/or pitch args makes it look in the completely wrong direction.
Using yaw and/or pitch args also causes the player to move very slightly. This has existed since at least 1.21.4 so not new problem.

Issues also happen with teleport command while riding entity but probably should be separate thread.
