A theme can opt-in for tailored starter content to apply to the customizer when previewing the theme on a fresh install, when `fresh_site` is at its initial `1` value. Starter content is staged in the customizer and does not go live unless the changes are published. Initial starter content is added to Twenty Seventeen.
* The `fresh_site` flag is cleared when a published post or page is saved, when widgets are modified, or when the customizer state is saved.
* Starter content is registered via `starter-content` theme support, where the argument is an array containing `widgets`, `posts`, `nav_menus`, `options`, and `theme_mods`. Posts/pages in starter content are created with the `auto-draft` status, re-using the page/post stubs feature added to nav menus and the static front page controls.
* A `get_theme_starter_content` filter allows for plugins to extend a theme's starter content.
* Starter content in themes can/should re-use existing starter content items in core by using named placeholders.
* Import theme starter content into customized state when fresh site.
* Prevent original_title differences from causing refreshes if title is present.
* Ensure nav menu item url is set according to object when previewing.
* Make sure initial saved state is false if there are dirty settings without an existing changeset.
* Ensure dirty settings are cleaned upon changeset publishing.

* Request full refresh if there are nav menu instances that lack partials for a changed setting.
* Restore `WP_Customize_Nav_Menus::$preview_nav_menu_instance_args` and `WP_Customize_Nav_Menus::export_preview_data()` from 4.3, and keeping a tally of all `wp_nav_menu()` calls regardless of whether they can use selective refresh.
* Ensure that all instances of `wp_nav_menu()` are tallied, regardless of whether they are made during the initial preview call or during subsequent partial renderings. Export `nav_menu_instance_args` with each partial rendering response just as they are returned when rendering the preview as a whole.
* Fix issues with Custom Menu widget where nav menu items would fail to render when switching between menus when a menu lacked items to begin with.
* Make sure the fallback behavior is invoked when the partial is no longer associated with a menu.
* Do fallback behavior to refresh preview when all menu items are removed from a menu.

When the same nav menu is shown multiple times on a page, only the first instance of the nav menu will include `id` attributes. Subsequent instances will have the `id` attributes omitted. However, in both cases the underlying nav menu item's post ID is available among the `class` names, so the post ID can be more reliably obtained from `class` instead of the `id` attribute.

* Introduce `WP_Customize_Manager::get_nonces()` to consolidate logic for retrieving nonces.
* Export nonces centrally in `wp.customize.settings.nonce` with each request and update nav menus preview to utilize.
* Send updated nonces to preview upon `nonce-refresh`.
* Request full preview refresh if Nav Menu selective refresh request fails (e.g. due to bad nonce).
* Update nav menus and widgets in Customizer to utilize `customize_refresh_nonces` for exporting nonces and keeping them up to date.

Add missing `params.completeCallback` to `MenuItemControl.focus()` for parity with `Control.focus()`. Also adds `params` to `MenuItemControl.expandForm`, `MenuItemControl.collapseForm()`, and `MenuItemControl.toggleForm()`.

* Fix a bug where updating the social menu links would cause the main navigation to get its toggle-expanded buttons duplicated.
* Persist any existing submenu expanded states on the updated menu.
* Improve naming of `customize-preview-menu-refreshed` event param from `wpNavArgs` to `wpNavMenuArgs` (old name is retained and marked as deprecated).

* When looping via `_.each`, pass `this` as 3rd arg to bind context
* Settings should be encapsulated in the module, instead of being exposed as static class props
* `currentRefreshMenuInstanceDebouncedCalls` should be encapsulated and renamed, instead of being the longest symbol in the entire codebase

Addresses regression introduced in [33138], where deleted menu items would not be removed from the preview, and changes to a location's assigned menu would likewise not preview. Also makes the binding of the setting change events more robust.

Also includes these related changes:
* Export `oldContainer` and `newContainer` among the `customize-preview-menu-refreshed` event params for themes to be able to more easily re-initialize the DOM elements.
* Improve performance for partial refresh by only sending settings related to the menu being previewed.
* Fix previewing of menu assigned to Custom Menu by exporting a menu `term_id` as opposed to an object, as the former is more stable for comparing in in args hashes.
* Do full refresh of preview when nav menu unassigned so that the layout can be updated.
* Harden conditions for when partial refresh is eligible for a `wp_nav_menu()` instance.

Defer the preview starting to listen to setting changes until after the Customizer has synced settings into the preview. This ensures that any differences between the JS and PHP representations of the settings won't cause an infinite refresh.
