 * Will prevent binding twice to the same element.
 * Initial state is expanded by default, this can be overriden by adding class
 * "mw-collapsed" to the "mw-collapsible" element.
 * Elements made collapsible have class "mw-made-collapsible".
 * Except for tables and lists, the inner content is wrapped in "mw-collapsible-content".
