/*
 * Info tips: a small "i" button that reveals a short explanation.
 *
 * Markup (see core/templates/core/partials/info_tip.html):
 *   <span class="info-tip">
 *     <button class="info-tip__btn" aria-expanded="false" aria-controls="id">...</button>
 *     <span class="info-tip__bubble" id="id" role="tooltip">Text</span>
 *   </span>
 *
 * Hover or keyboard focus shows the bubble; a tap toggles it (static/js/info-tip.js).
 * The bubble anchors to the nearest `.info-tip-anchor` (a label row) so it spans
 * that row and can never run off a phone screen.
