Subject: [PATCH] Fix bug in makeCollapsible. * The instantHide implementation
 (added in r82471) didn't cover the case where a table is collapsed by
 default, it needs to pass the toggle to the function so that the row it is in
 can be excluded. * The bug was found by user Helder.wiki, also reproducable
 on the demonstration page (I guess it was cached for everyone, since nobody
 noticed?) * Demonstration page has been refreshed and all tests are passed
 now.
