Description

Expected behavior

when a player mounts a horse, their y level increases by 0.85, the ride height of the horse, as indicated on their f3 and by running minecraft:tp ~ ~ ~ to get position, this should be reflected by player.getLocation().

Observed/Actual behavior

Calling player.getLocation() returns the y value of the player's vehicles feet as when they are not on the vehicle at all.

Steps/models to reproduce

Check every tick player.getLocation(), mount a horse, at for example y level 60, when you are on the horse it will correctly return your Y level as 60.85, but once you add a saddle, enabling control of the vehicle, the y level glitches between 60.85 and 60.0 randomly.

Research direction

Start by reproducing the issue with player.getLocation() while riding a saddled horse at a known Y level, comparing it with the in-game F3 display and minecraft:tp ~ ~ ~. Trace how player.getLocation() reports the vehicle and rider positions, then verify that the returned Y value remains consistently at the rider's ride height.
