/**
* 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;}
