 >However, note that the default value of the setting must still be a URL,
 since a default attachment id doesn’t really make sense.

 but when I specify the URL of an image as the default value for the
 control's setting, it does not appear in the Customizer.

 Here's the code I've added inside in twentyseventeen_customize_register()
 of wp-content/themes/twentyseventeen/inc/customizer.php:

 {{{
 /**
  * My Test.
  */
 $wp_customize->add_section(     'my-settings', array(
         'description' => __( 'Use the included default image or
 personalize your site by uploading your own image.<br /><br />The default
 images is <strong>1600 pixels wide and 1050 pixels tall</strong>.',
 'twentyseventeen' ),
         'title'       => __( 'My Section Background Image',
 'twentyseventeen' ),
 ) );

 $wp_customize->add_setting(     'my-custom-image', array(
         'default'           => sprintf( '%s/assets/images/sandwich.jpg',
 get_template_directory_uri() ),
         'sanitize_callback' => 'absint',
 ) );

 $wp_customize->add_control( new WP_Customize_Media_Control( $wp_customize,
 'my-custom-image',array(
         'section'     => 'my-settings',
         'label'       => sprintf( __( 'My Section Image:',
 'twentyseventeen' ), $image ),
 ) ) );
 }}}

 What I expect to see:

 [[Image(http://d.pr/i/d8OT+)]]

 What I see:

 [[Image(http://d.pr/i/PYft)]]

 If I specify an attachment ID, it works.

 It would be of great convenience if this works by specifying image URL
 rather than ID especially when we are inside a foreach loop where we can
 use the placeholders for outputting the default images (like bg-1.jpg,
 bg-2.jpg).

 If I replace WP_Customize_Media_Control with WP_Customize_Image_Control,
 the default image appears fine.
