Auto merge of #15794 - paulrouget:head_parsed_url, r=asajeffrey

Browse source 
Notify embedder when history changes

`WindowMethods::set_page_url` is only called when the embedder set the URL. It is not called when the page url is updated. I believe that instead we should just pass the URL to `head_parsed`.
