 As far as I know, there is no way to display an error to the user when
 he/she is using the theme customizer.

 An error that I'm facing some time to time when I test WordPress locally
 is when `wp-content/uploads` is not writable. Then, uploading a new image
 to use as a background in the customizer does not work, but this fails
 silently.

 This error reporting should be built-in inside `WP_Customize_Control`
 class so that any control that extends this class can throws a custom
 error and displays it to the user.

 Depends on #35210.
