/**
 * Make thead top and tfoot bottom sticky for JS wikitables and sortable tables.
 *
 * Issues:
 * - Broken borders. https://bugs.webkit.org/show_bug.cgi?id=128486
 * - Sticky sorttop/sortbottom after sort: T355492.
 * - Timeless wide tables in overflowable boxes, so not sticky.
 * - Mobile tables in overflowable boxes (display:block), so not sticky.
 * - Other tables in overflowable boxes not sticky without vertical scroll.
