 */

/**
 * Adds a visual highlight style to an attribute element in which the selection is anchored.
 * Together with two-step caret movement, they indicate that the user is typing inside the element.
 *
 * Highlight is turned on by adding the given class to the attribute element in the view:
 *
 * * The class is removed before the conversion has started, as callbacks added with the `'highest'` priority
 * to {@link module:engine/conversion/downcastdispatcher~DowncastDispatcher} events.
 * * The class is added in the view post fixer, after other changes in the model tree were converted to the view.
 *
 * This way, adding and removing the highlight does not interfere with conversion.
 *
 * Usage:
 *
 *		import inlineHighlight from '@ckeditor/ckeditor5-typing/src/utils/inlinehighlight';
 *
 *		// Make `ck-link_selected` class be applied on an `a` element
 *		// whenever the corresponding `linkHref` attribute element is selected.
 *		inlineHighlight( editor, 'linkHref', 'a', 'ck-link_selected' );
 *
 * @param {module:core/editor/editor~Editor} editor The editor instance.
 * @param {String} attributeName The attribute name to check.
 * @param {String} tagName The tagName of a view item.
 * @param {String} className The class name to apply in the view.
