Well, it's actually working fine for me.

You should not need to copy any CSS or JS to enable Show/Hide features, because it's built into the software by now (as can be seen on Help:Collapsing). Your templates are coded to the old version of show/hide, but unless you choose to remove the CSS/JS anytime soon, that should be no problem.
