/**
 * This file contains an *adapter* for css-select. css-select is a CSS selection
 * engine for HTML that can be used with other data structures (XML, etc) via
 * adapters. Here we define an adapter for MathBox's vdom.
 *
 * The adapter interface is described here:
 *    https://github.com/fb55/css-select/blob/1aa44bdd64aaf2ebdfd7f338e2e76bed36521957/src/types.ts#L6-L96
 *
 * Nodes vs Elements:
 * In general, CSS Selectors act on a document tree built from nodes, which can
 * include element nodes and non-element nodes. For example, in HTML, tags are
 * element nodes but lines of text are non-element node. Non-element text nodes
 * can influence css selection, e.g., via :first-line pseudoclass, but these
 * non-element nodes are never returned by selectors.
 *
 * Mathbox only has element nodes.
