       * - Parsing means that the anchor's `protocol`, `hostname`, `port`, `pathname` and related
       *   properties are all populated to reflect the normalized URL.
       *
       * While this approach has wide compatibility, it doesn't work as expected on IE. On IE, normalizing
       * happens similar to other browsers, but the parsed components will not be set. (E.g. if you assign
       * `a.href = 'foo'`, then `a.protocol`, `a.host`, etc. will not be correctly updated.)
       * We work around that by performing the parsing in a 2nd step by taking a previously normalized URL
       * and assigning it again. This correctly populates all properties.

       * https://github.com/angular/angular.js/blob/2c7400e7d07b0f6cec1817dab40b9250ce8ebce6/src/ng/urlUtils.js#L26-L33
