/* !important here is intentional: another stylesheet (pages.css, styles.css,

   higher specificity, which strips position:relative from a nested <li>.
   When that happens, that item's own absolute-positioned child dropdown has
   no positioned ancestor to anchor to nearby, so the browser walks up the
   DOM until it finds one — usually the sticky header — and the dropdown
   renders detached way up at the top of the page instead of next to its
   parent item. Forcing this at every depth guarantees it can't happen. */
