/**
 * Wrap each text node in a given Node or Range with a `<mark>` or other
 * element.
 *
 * If a Range is given that starts and/or ends within a Text node, that node
 * will be split in order to only wrap the contained part in the mark element.
 *
 * The highlight can be removed again by calling the function that cleans up the
 * wrapper elements. Note that this might not perfectly restore the DOM to its
 * previous state: text nodes that were split are not merged again. One could
 * consider running `range.commonAncestorContainer.normalize()` afterwards to
 * join all adjacent text nodes.
 *
 * @param target - The Node/Range containing the text. If it is a Range, note
 * that as highlighting modifies the DOM, the Range may be unusable afterwards.
 * @param tagName - The element used to wrap text nodes. Defaults to `'mark'`.
 * @param attributes - An object defining any attributes to be set on the
 * wrapper elements, e.g. its `class`.
 * @returns A function that removes the created highlight.
