 Related to [52829] is this PHP Notice that seems to be triggering on a
 `the_content` filter after that change:

 {{{
 GET https://wordpress.org/news/2014/04/smith/

 E_NOTICE: Undefined index: scheme in wp-includes/canonical.php:854
 Undefined index: scheme
 }}}

 The input in this case is a URL such as
 `//wordpress.org/news/files/2014/04/widgets.mp4`.

 I also note that `strip_fragment_from_url()` doesn't use `wp_parse_url()`
 but uses `parse_url()` directly.
