Collision Doesnt work with place_box Active, On Div

Hey guys im trying to wrap my head around some jquery stuff i seem to have found the issue within place_box() affecting my code. 


Issue is i was my dragable/movable div to stay within the wrapper. but when i enable the Event key_handler() to move the div with WASD i am able to sneak out of the div! Any help would be awesome. Thanks

I have attached the example code, 

Now if Place_box() is commented out it work great on the drag but then the WASD movement keys just dont work!

Thanks
