   NOTE: position:fixed (not absolute) is used deliberately. The .tabs bar

   the CSS spec that forces overflow-y to compute as "auto" too — which
   would silently CLIP an absolutely-positioned dropdown living inside it.
   Fixed positioning escapes that clipping. Its exact top/left coordinates
   are calculated in JS (see site-script-v4.js) from the trigger button's
