 In Twenty Seventeen we add preconnect for Google Fonts via
 `wp_resource_hints`.

 In there we check that styles are enqueued: `wp_style_is(
 'twentyseventeen-fonts', 'queue' )`.

 In child theme it's pretty common that we dequeue parent fonts and load
 our own Google fonts: `wp_dequeue_style( 'twentyseventeen-fonts' );`

 This means that our `wp_style_is` check is `false` and our preconnect code
 is not printed anymore.

 Could we change the check like this so that preconnect would be in child
 themes also. For example:

 `wp_style_is( 'twentyseventeen-fonts', 'registered' )`.

 Downside is that child theme can use other than Google fonts also. Anyways
 I just wanted to put this out here for discussion.
