      * @description
      * Sanitizes an html string by stripping all potentially dangerous tokens.
      *
      * The input is sanitized by parsing the HTML into tokens. All safe tokens (from a whitelist) are
      * then serialized back to properly escaped html string. This means that no unsafe input can make
      * it into the returned string.
      *
      * The whitelist for URL sanitization of attribute values is configured using the functions
      * `aHrefSanitizationWhitelist` and `imgSrcSanitizationWhitelist` of {@link ng.$compileProvider
      * `$compileProvider`}.
      *
      * The input may also contain SVG markup if this is enabled via {@link $sanitizeProvider}.
      *
      * @param {string} html HTML input.
      * @returns {string} Sanitized HTML.

      * Requires the {@link ngSanitize `ngSanitize`} module to be installed.
      *
      * @param {string} text Input text.
      * @param {string} target Window (`_blank|_self|_parent|_top`) or named frame to open links in.
      * @param {object|function(url)} [attributes] Add custom attributes to the link element.
      *
      * Can be one of:
      *
      * - `object`: A map of attributes
      * - `function`: Takes the url as a parameter and returns a map of attributes
      *
      * If the map of attributes contains a value for `target`, it overrides the value of
      * the target parameter.
      *
      *
      * @returns {string} Html-linkified and {@link $sanitize sanitized} text.
