/**

* Normalizes and parses a URL.

*
|
|
* - Normalizing means that a relative URL will be resolved into an absolute URL in the context of
|
|
* the application document.
|
|
* - 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.
|
|
