/*
 * Aya's Doc framework supports two popup kinds:
 * (1) Hover (used in code: `Doc.HyperLinked`): shows extra information (in code: `String`) on hover. The hover is implemented in pure CSS.
 *     Pros: it can be rendered correctly in more places, (like some markdown renderers don't support JavaScript).
 *     Cons: the popup content is not clickable, selectable, or copyable. Users cannot interact with the popup.
 * (2) Tooltip (used in code: `Doc.Tooltip`): show a separate document (in code: `Doc`) on hover. The tooltip is implemented in JavaScript.
 *     Pros: support everything that a normal HTML document can do, e.g. clicks, selections, copy-paste.
 *     Cons: if the renderer doesn't support JavaScript, so the tooltip won't be rendered.
