Can't properly cancel entity movement with passengers or for vehicles

Expected behavior

Entity move event should be called even with passengers

Observed/Actual behavior

Vehicles can't enter unless steered into the region

Player movement is cancelled, but the mount can freely move

Mobs without passengers can't enter (intended)

Steps/models to reproduce

1. Cancel player, vehicle and entity movement into a certain region
2. Try to walk into the region (should and does not work)
3. Try to push a mob or vehicle into the region (should and does not work)
4. Steer a vehicle (horse, boat, pig, strider) into the region (glitches out like crazy because player movement is still called for some reason, but the player stays mounted, and the vehicle keeps moving)
5. Steer a minecart into the region (should not, but does work. When dismounting, the player is teleported back to their supposed position)

My code for cancelling the movements

@EventHandler(priority = EventPriority.HIGHEST, ignoreCancelled = true)
public void onPlayerMove(PlayerMoveEvent event) {
    if (!event.hasChangedBlock()) return;
    if (canMove(event.getPlayer(), event.getFrom(), event.getTo())) return;
    event.setCancelled(true);
}

@EventHandler(priority = EventPriority.HIGHEST, ignoreCancelled = true)
public void onEntityMove(EntityMoveEvent event) {
    if (!event.hasChangedBlock()) return;
    if (canMove(event.getEntity(), event.getFrom(), event.getTo())) return;
    event.setCancelled(true);
}

@EventHandler(priority = EventPriority.LOWEST, ignoreCancelled = true)
public void onVehicleMove(VehicleMoveEvent event) {
    if (canMove(event.getVehicle(), event.getFrom(), event.getTo())) return;
    // event.getVehicle().setVelocity(new Vector());
    event.getVehicle().teleport(event.getFrom());
}

Start by reproducing the listed vehicle, passenger, minecart, and entity cases with the PlayerMoveEvent, EntityMoveEvent, and VehicleMoveEvent handlers shown in the issue. Trace how movement cancellation and teleportation interact, then verify that blocked movement consistently prevents vehicles and passengers from entering the region without the reported glitches.
