+ * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
  * browsers.  However, the parsed components will not be set if the URL assigned did not specify
  * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
  * work around that by performing the parsing in a 2nd step by taking a previously normalized
  * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
  * properties such as protocol, hostname, port, etc.
  *
- * IE7 does not normalize the URL when assigned to an anchor node.  (Apparently, it does, if one
- * uses the inner HTML approach to assign the URL as part of an HTML snippet -
- * http://stackoverflow.com/a/472729)  However, setting img[src] does normalize the URL.
- * Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception.
- * Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that
- * method and IE < 8 is unsupported.
