Describe the bug

private ServerLocation pos = null;
    
    @Listener
    void onMove(MoveEntityEvent event, @Getter("entity") ServerPlayer player) {
        if (player.world().block(event.destinationPosition().toInt()).type() == BlockTypes.WATER.get()) {
            player.sendMessage(Component.text("water hit"));
            event.setDestinationPosition(pos.position());
        }
    }

    @Listener
    public void onRegisterCommands(final RegisterCommandEvent<Command.Parameterized> event) {
        event.register(this.container, Command.builder().permission("teleporttest.command.greet").executor(ctx -> {
            var player = ctx.cause().last(ServerPlayer.class).orElseThrow();
            pos = player.serverLocation();
            ctx.sendMessage(Component.text("true"));


            return CommandResult.success();
        }).build(), "setenable");
        
    }

When a player has a bit of delay to the server, MoveEntityEvent.setDestinationPosition teleports the player to the wrong position. I have tested this on a vanilla client, so it is not caused by client-side mods.
