 * The tooltip is positioned via JavaScript (see static/js/glossary.js) using
 * `position: fixed`. This is necessary because the tooltip's natural ancestors
 * include things like `.table-wrapper { overflow-x: auto }` (see
 * layouts/_default/_markup/render-table.html), and any `overflow: auto|hidden|
 * scroll` ancestor clips absolutely-positioned descendants. A fixed-positioned
 * tooltip sits in the viewport, escaping every ancestor overflow context.
 *
 * JS sets `top`/`left` on hover/focus, then unsets them on leave/blur.
