/**

 * Make first row or thead element top sticky.

 *

 * Div class (optional):

 * - sticky-header-scroll: contain table; restrict height/width; sticky headers

 *   when vertical scroll visible (table taller than 75vh screen).

 *

 * Table classes:

 * - sticky-header: sticky first row.

 * - sticky-header-multi: sticky thead; headers moved via sortable + JavaScript.

 *

 * Tested:

 * - Windows 10: (all skins) Chrome, Firefox, Edge.

 * - Android Galaxy S21 (Minerva): Chrome, Firefox.

 * - iPhone SE 2020 (Minerva): Chrome, Edge, Firefox, Opera, Safari.

 * - Wikipedia Android app.

 * - Print: Not styled.

 * - No JavaScript.

 *

 * Notes:

 * - Sortable moves to thead any header rows and (after sort) sorttop rows.

 * - Sticky gadget (.mw-sticky-header) moves to thead any wikitable header rows.

 *

 * Issues:

 * - Monobook width <=550px not sticky unless "sticky-header-scroll".

 *   Can't override:

 *   body.skin--responsive .monobook-body {overflow: auto;}
