Comment (by westonruter):

 @joemcgill something to be aware of with [39272] specifically with using
 `esc_url_raw` as a `sanitize_callback`: when the customizer invokes that
 callback it passed the `WP_Customize_Setting` instance. So here what this
 means is that the setting instance would get passed in as the `$protocols`
 parameter. For this function specifically, fortunately if `$protocols` is
 not an array, then it gets set to `wp_allowed_protocols()`, so it will
 work as expected. But this is something to be aware of in general.
