-no need to run mouseleave if stack height is already collapsed height (and of course collapsed height exists) (im thinking this is good practice, because if it runs mouseleave then it adds transitionend function, which i dont think executes, just tested it, it DOES not execute, i think mainly because my css says not to execute, but im leaving this here because if its disabled it should go to collapsedheight right away is fine)
