 In [changeset:"35308"]:
 {{{
 #!CommitTicketReference repository="" revision="35308"
 Customizer: Prevent `nav_menu_item` settings from becoming dirty when
 their controls are set up.

 Since `wp_setup_nav_menu_item()` returns the `classes` property as an
 array but the Customizer manages the value as a string, the setting needs
 to initially export the value as a string. This prevents the `classes`
 property type change from causing the setting to get marked as dirty even
 though nothing changed. This is a regression from [34788].

 See #34111.
