Component:  General       |    Version:  trunk

 As noted in https://wordpress.org/support/topic/ordering-of-dns-prefetch-
 preconnect?replies=2, the resource hints should be printed '''before'''
 scripts and styles are returned.

 The current priority is 10 for `wp_head` and for the admin we're using
 `admin_head` which runs after `admin_print_scripts`. We can lower the
 priority to 1 for the front end and should change the admin hook  to
 `admin_print_styles`.
